The three-speed 3T40 transmission was very popular at GM. This build was formerly called the TH125. In 1992, big changes took place that changed how gearboxes were referenced. General Motors ended up marketing the very 3T40 transmission for sale on this page. These are offered as rebuilt or used to PTG buyers.
The hydramatic series of gearboxes were doing well decades before controls were set by electronics. The use of hydraulic controls was a standard for a number of years. The converter clutches were a type of technology on some variations of the AWD 125C gearboxes. GM made the transverse units electronic for better stability.
Reconditioned THM Gearboxes
There were cars and vans that ended up having the 3T40 installed. Although this was only a 3-gear model, it was tuned just right for a variety of motor vehicles. It was the electro-controlled 4T40E that put the turbo-hydramatic model to bed for good in 1995.
Even though mass production is not in force, there are many ways that a person can find a rebuilt 3T40 transmission online. Without checking our inventory, there are retailers and single shop owners that provide variations of these assemblies. PTG owns its own equipment and facility to rebuild all models.
