Dorman TECHMs, at least a few years ago, had a very high faulty rate. Stick with GM OE if replacing the whole thing. Alternatively, you can rebuild it on your kitchen table with this kit:


That's the tool!
and that price is terrible, but it seems to be the going rate right now... weird.

I paid about $40 for mine

(I don't know what the difference is, but this is the one i used for my 6l80)

Sonnax also has a kit to replace the laminates and seals.
At a minimum, make sure you have an extra set on hand.

For me; those laminates seem to have a learning curve. :jester:


I had a sec and found some parts,
(I should probably add it to my build thread for safe keeping... lol)

Important as it also comes with the needed seals.

Sonnax tool - 124740TL30 - 6L45 6L50 6L80 6L90 6T70
also search for "124740-30K" finds it with prime

Transgo SK6L80 Shift Kit

This goes with the above kit (mentions the pn in the shift kit instructions)
Transgo 6L8CSTCC Valve Kit

Missing are the sonnax check balls, out of time to find the pn for ya.
And a bunch of this i bought locally from trans star, so i don't have it in my order history.

The pan gasket should be reusable, and it's like $20 if you need to replace it.
I didn't but i have a spare on hand.

Filter kit,
