Alot has changed in the automotive industry since opening and we strive to keep up with these changes through attending several seminars, keeping up with the latest diagnostic tools and technical information. In many cases we can make your transmission work better and last longer than the original.
We are one of the few shops that still perform a complete transmission service. Most places are just flushing the fluid out and not changing the filter. You would not change the engine oil without changing the filter, nor should you with your transmission when it is accessible. We service them like we would are own.Performing a test drive and scan of the vehicle, removing the pan and cleaning, replacing the filter and flushing the system as well as any re calibration needed. Ask for the ultimate transmission service and give your car the proper care it needs.

Tech Tip from Clutch & Transmission Technicians
We at CTT have compiled some information from years of experience that will help you save time and money, as well as an over all better experience and understanding when taking your vehicle in for repairs.
It doesn’t have to be scary or nerve racking when your vehicle is giving you trouble.
Here are some tech tips on things you can do to help your trip to the local shop go smoother.
1: Before even calling around to find a shop.
Today’s electronically controlled vehicles are common to have intermittent problems that are hard to duplicate. By following the procedure below, it can help save time and costly diagnostics.
Take some time to get the information you need to explain the problem in detail.
- If the problem is intermittent. Put a noted pad and pen in the vehicle and right down detailed information on the problem.
- Did the problem occur after driving in stop and go traffic, after driving 2 hours, when vehicle is cold in the morning or after warmed up, when the weather is cold or hot.
- Was the problem intermittent? If so, when did it occur and when did it clear itself up.
- Was there a check engine light or any other dash lights that came on and did they go out or stay on.
- Were any other repairs or accessories added recently before the problem occurred?
- Add any information that you think may be helpful. Keep in mind, there is no dumb information.
2: Ask friends, family and co workers for referrals.
It is always better if you can get a referral but reviews are always another good alternative.
3: Make sure the shop can perform the work that you are needing. Today’s vehicles are very complex and often, their is specialty shops for different repairs. Sometimes the shop will sublet the work out to a specialty shop. It is better to have the repair done at the shop you are dealing with. The better you can explain the problem, will help the service adviser you call to determine whether this is something they can do or refer you to another specialty shop and avoid going to a few different shops to resolve the complaint.
4: Noises are one of the hardest problems to diagnose and are often diagnosed wrong.
As a technicians we are constantly listening for any noises that are not normal. This does not mean that it is the noise that you are wanting repaired. By following these steps below. It will help get the noise repaired correctly, the first time.
- Describe the noise in detail
- Does it happen when hitting a bump, when turning on an accessory, at higher speeds or lower speeds, when accelerating or decelerating, turning corners etc.
- It it a chirp, growling, buzzing, ticking, grinding, rattle etc.
- It is best to ask the technician to go for a ride and duplicate the noise
5: Don’t be in a hurry when dropping your vehicle off. Leave plenty of time to explain the problem in detail and even go for a test drive if necessary. Try and drop the vehicle off your self. Often the problem does not get described properly when another person is dropping off the vehicle. If you can not, then it is a good idea to give the shop a call and describe the problem in detail.
6: Do not be afraid to give the shop a call back if you think of some new information that may help them with the complaint.
We have test driven vehicles for a few days without being able to duplicate a problem, and then the customer has remembered something that allows us to duplicate the problem.
7: Once the vehicle has been checked out and they give you an estimate for the repair. Make sure you understand the work they are going to be doing and that it is going to resolve the problem you were experiencing. Ask for a worst case scenario if something has to be torn down further to inspect.
8: As with dropping the vehicle off. Leave lots of time for the technician or service adviser to explain what they have repaired and if there is any maintenance or further repairs that may need to be done. Don’t be in a hurry. Try and pick the vehicle up in person instead of having someone else pick up the vehicle as sometimes, things get lost in the translation. we know it is sometimes hard to do this with busy schedules and work hours. If this can not be done, it is a good idea to give the shop a call later to find out this information.
We hope this information will save you time, money and frustration on your next trip to your local shop

If you have 4WD Chevrolet or GMC Diesel Truck with the Allison Transmission, we recommend reading this article.
This article addresses a code PO735, typically after driving at higher speeds. May also have a trans overtemp code.
Conditions that usually set code: This code will usually set when you are driving at higher speeds and you feel the transmission down shift or neutral out, followed by a check engine light. It can also set when pulling a trailer at freeway speeds, then accelerating to pass. This tends to happen more on vehicles that are used for towing and or have been modified for extra horsepower. When this code sets. It puts the transmission into a fail safe mode and will eliminate 5th gear and lockup. This will cause the transmission temperature to rise and get hot. We recommend pulling over as soon as possible and not driving like this or damage to the transmission could occur.
Immediate action: We recommend pulling over to a safe place and checking for codes. If you get a code PO735 5th gear ratio. We recommend writing the code down for future reference and clearing the code. ( We recommend buying a code reader and keeping it in the vehicle for this purpose. One that can also clear codes) Check your transmission fluid condition and level. If the fluid level is good and the color is a clear pink and does not smell burnt . Then check the transfer case fluid. This will require getting under the vehicle, so only do so if the vehicle is in a safe place to do so and is secured from rolling. If the transfer case or transmission fluid is low or burnt. We recommend towing vehicle to the nearest shop.
Buying a Car in 2018
There are many pros and cons to look at when buying a vehicle, whether it be new or used cars.
We are going to go over the transmission which has never been more important.
The CVT Transmission.
There are several things to consider before purchasing a vehicle but we think this should be at the top.
What to look out for from a transmission shop side of view with so many CVT Transmissions out there.
We at Clutch & Transmission Technicians have been serving Modesto for the past 26 years and would like to help shed some light on the CVT transmission. We love to give back to our community and hope this will help people from finding out after the purchase when they are looking at an expensive repair tag that they have a CVT Transmission.
Know what you are purchasing!
Yes CVT, Constant Velocity Transmission. Store this in your phone and make it one of the top considerations when buying a vehicle. A CVT Transmission is a belt driven transmission that is picking up momentum in the automotive industry and found in the majority of small to medium sized vehicles today.
The difference between a cvt transmission from traditional automatic transmissions is that they don’t have gears that provide steps between low and high speed. Instead, the majority of them work via a pair of variable-diameter, cone-shaped pulleys connected by a steel or composite belt.
Do some research on them and determine if this is a transmission you want in your vehicle. We will go over some of the pros and cons of the cvt transmission in this blog, but a quick search on the internet will bring up loads of information. This is one of the first things we want you to research when buying a vehicle and narrowing down what your next purchase will be. We are still getting customers in on a regular basis that had no idea that they had a cvt transmission or that they even existed. This is why we are going to revisit this topic.
Pros: They are smaller and light weight compared to the traditional transmissions and are designed to improve fuel economy. Typically you get a smoother shifting transmission as well.
Cons: They are a weaker transmission and tend to have a lower torque delivery. They tend to do ok under normal driving but lack on harder accelerations. We service the Modesto and surrounding area and are seeing some of them fail at low mileage and come with a pricey repair tag. At this point, there aren’t a lot of quality parts available to repair them and we are having to install dealer units.
Our advise on buying a vehicle with a cvt transmission.
When to buy a vehicle equipped with a cvt transmission.
If you test drive the vehicle and are happy with the way it drives and how it transfers the power under harder throttle. You are not planning on keeping the vehicle past the warranty period or buying an extended warranty. This may be a good option for you.
When not to buy a vehicle with a cvt transmission.
If you plan on keeping the vehicle past the warranty period and like the way a traditional transmission shifts and the way the power is transferred. This may not be the option for you. Reselling the vehicle when it comes time, may be an issue also if the consumer has done their research or had any dealings with a cvt in the past.
In summary, cvts are here to stay and a large percentage of the vehicles come with them. As time goes on, the parts will become better and more accessible bringing the cost to repair them down. They should also become more reliable and the life expectancy should increase. For now, we at CTT Transmissions would not recommend purchasing a vehicle with one unless you are going to sell it or trade it in before the warranty period is up.
How do I know which vehicles have a cvt?
We would not recommend relying on the salesman or owner of the vehicle as they may not even know if it has one. A quick search on the internet using different terms such as the year, make, model and engine size asking if the vehicle comes with a cvt should produce several sites with this information. They have been out for a while now but they have gotten really popular in 2013 with the majority of the manufactures using them, mostly in the compact vehicles.
If you have a cvt transmission and it fails at low mileage but is out of the standard warranty, contact the dealer and see if they have extended the warranty on it before having it replaced.
CTT Transmissions 700R4
Transmission Tech Tip
The Modesto transmission shop you can rely on.
The 700R4 transmission is one of the most popular transmissions used in hot rod applications today. Hot rod enthusiasts like it as it has a low first gear and an overdrive gear. It drops the rpms approximately 600 rpms in high gear vs a turbo 350 or 400 3speed transmission. It was used from 1982 to 1992 in a wide variety of vehicles. The best year to use for performance is 1988 up. The stock transmission had many issues and we were seeing them fail at low mileage. Some updates were done over the years from the factory to help them last but most were not addressed. However there are several updates available aftermarket that make them perform and last much better.
We have perfected this transmission over the years and have a unique method of making them perform at their best in a wide variety of vehicles. We have done conversions on many different vehicles, from 1800 lb street rods to 6,000 lb trucks with 3:08 gears to 4:11 gears. When you order a transmission from us, we will pull one off the shelf and customize it to your specific vehicle and when it is installed, we will adjust it for free. This is the difference between enjoying your 700R4 transmission and being frustrated with it. “transmission not set up for your vehicle = bad“, ” transmission set up for your specific vehicle = good” Visit our site at https://www.ctttransmissions.com/high-performance.html
We are privileged to be in such a great area for car shows. With Graffiti taking place in Modesto every year and hundreds of area cars shows. We get to see and work on some of the nicest hot rods and muscle cars in the country. Visit our website gallery https://ctttransmissions.com/techtalk/galleries/ to see some of the vehicles that have came through our shop.
We sell bench units or do the complete conversions for those that just don’t have the time or space.

It has been our pleasure to have had the chance to work on some of the nicest hot rods in the Central Valley and places as far as Reno, San Francisco and Monterey. We also stock most of the parts needed for the conversions and our techs are more than happy to help with any questions you may have to help make your conversion as easy as possible.

Transmission Tech Tip: Ford 7.3 Diesel Transmission overheating
7.3 to 6.0 transmission cooler swap
We get calls often on the 7.3 diesel with automatic transmission overheating when pulling steep inclines with trailers. There can be several factors that will cause a transmission to overheat. It should always be diagnosed first. The temp sensor could be faulty, the fluid could be low or need to be changed or there could be internal problems. The 7.3 diesel tends be under powered and can cause extra pressure and heat in the transmission when trying to pull steep hills, but replacing the transmission cooler with the newer 6.0 diesel cooler makes a huge difference. We recently replaced the cooler on a F350 with a 7.3 that was reaching temperatures of 240 degrees when pulling their 40 ft. toy hauler up the grapevine. They called us and were very impressed as they pulled the same hill under the same conditions and only reached 185 degrees. You can add deeper pans with fins and we recommend a synthetic fluid but the cooler will make the biggest difference and is a must on the 7.3 engine.
