Chevrolet Transmission Repair Signs & Symptoms

Here are some clear indications that your Chevrolet transmission needs to be looked at:

Burning smell: It could be cause by a number of issues, but if the burning smell is not coming from the tires, it might be your transmission!
Noise: Your car should never make any loud or knocking sounds when idling.
Gear slippage: Are you having a hard time shifting gears, or does it take longer to shift than normal?
Leaking fluid: This is a huge indication that something is wrong with your vehicle!
Check engine light: This may not be your transmission, but it is definitely a problem–especially accompanied by any of the above signs!

Specific Issues with Chevy Transmissions

4L60E Transmissions: With these transmissions, there are several points of failure:

The sun shell splines, as these can strip off
The hub containing the splines breaking off, causing you to lose 2nd, 4th, and reverse gears.
Another common problem is the 3/4 clutches and 2/4 bands get burned up.

All Chevrolet 4L60E Transmissions get a new hardened sun shell with every rebuild, and we use high energy lined clutches and bands to ensure a long life from these components. These are just a few of the many upgrades we do on every Chevrolet transmission that comes through our shop. We want to make sure that our customers are able to enjoy their vehicles for many more miles to come.

With over 25 years experience our Master Transmission Builder has the knowledge and expertise to get your Chevrolet back on the road. We are so confident in our transmission rebuilding that we give every transmission that comes through our shop a 12-month, 12,000 mile warranty FREE.

We’ll give you a fair estimate, providing our diagnosis and recommendations. Our mechanics will work with you to determine whether a repair or complete rebuild is the smartest way to progress.
