Re: trannys

This is why I don't understand why GM didn't include trans temp gauge like the engine gets. Either one goes out and your stuck with big repair bills yet only engine is watched. Bad move on GM's part.

Re: trannys

( temp gauge) ...I was told by a performance transmission builder that installing a tranny temp gauge will drive a driver nuts!! The temp climbs up and down so much.

I installed a Seatrab cooler. I won't use the radiator for cooling.....

I, too, learned my lesson....

2 things kills your tranny... over heat & an improperly adjusted throttle cable ( fluid pressure).

Fair enough. How about an overheated light of doom then?

What was the problem with the rad/trans cooler? Completely clogged?
