Trade names

What the transmission names mean in Pontiac

The list above shows the code a mechanic reads: the code from the plate, the parts catalogue number or the design symbol. In a search engine people type something else: the transmission model name or the showroom name. These describe the same transmission. Below are the ones that appear in this list, together with the clutch type, because that decides how the repair runs and what it costs.

Transmission model Trade name Gears Clutch Torque Layout
4L60E Hydra-Matic 4 torque converter longitudinal
6T40 Hydra-Matic 6 torque converter 240-280 Nm transverse

Maximum torque is the highest torque the transmission can safely handle without risk of damage. It is the factory figure for the transmission model, not for one particular car. Some codes from the plate have no publicly confirmed model assignment, and those stay in the table without a second name. The VIN number is what finally decides, which we check before you arrive.

Gearbox trouble in your Pontiac? Write to us

Describe the symptoms: at what speed they appear, with the engine cold or warm, whether there is a jolt when shifting, a delay after engaging a gear, or a message on the dashboard. Add the model year, the engine and the VIN. We will write back with what that suggests and which check makes sense. Whether we take the repair is decided by the diagnostic check.
