wifes car thru a P1811 code the other day, only does it when its 90 degrees plus outside and the tranny gets up to temp. Brought it to a shop and wasted $100 having them look at it, quoted 3800 for new transmission, i laughed.

Car has 127,000 miles on it, tranny flushed every 30k. Rest of car is solid, just got done putting all new brake and fuel lines in myself.

Anywas I was thinking of trying, replace pressure control solenoid (going to order from rock auto, AC delco) and a transgo SK 4t65E shift kit (already have in hand).

So my question is, does this seem like a reasonable approach? and is there a good tutorial on how to get access to this? I know you have to drop subframe and title engine toward driver but doesn't seem that bad.

Mind you I have replaced the power steering rack a while back so this won't be that much different, in my mind.

I am planning on buying the K-tool engine support bar because I am sick of using wood and ratchet straps on other cars too.
