After contemplating this mod for a coupla years now, finally did it this morning. It went pretty smooth, no corrosion to deal with but getting the circlip out gave me a bit of a challenge, 5 different sets of circlip pliers and none of them would grab worth a darn, maybe the holes are metric sized...Didnt have an issue putting it back in place tho.

I have the plate style holding the trans lines. Beware the two o-rings on each line, one stayed in the block when I removed it, just watch you dont lose either. 10 and 13mm ratchet wrenches to remove, added a 10mm stubby ratchet wrench when installing due to exhaust pipe.

I did some test runs afterwards with "4 stop and look for leaks", quite happy with the results.

Excuse my ignorance,  is there a performance betterment in changing this thermostat?

 

Or is it a part that needs watching out for?

 

Thanks

My take on it is: It reduces the higher running temperatures that the transmission see's by about 30 to 50 deg F. Transmission (fluid) & transmission seals degrade faster at higher temperatures, so should allow stuff to live longer, than at the 185 to 200 deg F.

Does the 8 speed have a similar t-stat?

Yes. It looks identical, I’m pretty sure it’s the same part. I did the pill flip in my 8 speed

If the OP destroys the original trying to "fix" it he'll really be without a paddle. (or a truck for that matter too.)

Negative
