T42 GM TCU insides.

Post by 80gus »

Making a T42 to T43 bench flashing adapter and decided to kill a T42 to use th plug, was pretty surprised to see how small the insides were.
Thought otheres may be interested in seeing inside.
Mostly constructed well but simply whiping the gel of inside I had a component fall off the board like it was never soldered.

Try whipping open a E55

Now that’s twice as bad!

I'm not sure what your trying to do with adapter?

I just have a separate adapter for each tcm.

When i made my bench harness i should have put a plug to remove the tcu connector (just has t42, it was just a easy way to add another trans, to
my bench harness with a long lead with what components i have in the shop) probably not going to go this way as its to hard to successfully solder to the inside of the t42 connector.

Generally there is only 5 wires needed(some of the same spline off) but easier to make plug & play for each setup rather then make adapters! But that's only my opinion!
