Finding the right GMC transmission
GMC uses the same transmission families as Chevrolet, and each family covers many models. That makes a good used unit easier to find — as long as you match the right version.
Two transmissions with the same name can still differ by engine, drivetrain and model year, and a Denali often had a different unit from an SLE with the same engine. Give us your VIN and we’ll match it.

FAQ
Used GMC transmission questions, answered
How do I know which transmission my GMC has?
The transmission’s RPO code is on the Service Parts Identification label — for example M30 for a 4L60-E or MYC for a 6L80. We can also identify it from your VIN.
Will a Chevrolet transmission fit my GMC?
Usually, yes — the twins share transmissions. The unit still has to match your engine, drivetrain and model year, so send us your VIN and we will confirm.
Does a replacement transmission need programming?
Often, yes. Six-speed and newer GM automatics have a control module that usually has to be programmed to the vehicle after fitting. Your installer can confirm what your model needs.
Does a used GMC transmission come with a warranty?
Yes. Every transmission we sell is covered by warranty, and extended cover is available at extra cost. The full terms are in our Warranty Policy.
