Im looking for some help with a problem that started out of nowhere on my 4l60e tranny. After letting the car sit for a day without driving it (only spraying the engine compartment down to clean it off) it started with not shifting out of first gear until about 2500rpms only if i let of the gas. If i didnt the rpms would keep climbing without shifting. All the other gears shift fine at the correct rpms with no problem. that is the only problems until i punch the gas while moving. instead of downshifting it will redline until i let off. Can anyone please help with what might be causing this, i would really appreciate any help you may have.

What mods do you have. Could be alot things. Tuning issues? Hows the fluid level?

What Rpm Does It Idle At?

Maybe you hosed down the TPS and you are getting a bogus signal which would directly affect shifting. These sensors don't take too kindly to pressure washing.

would you put your T.V in the dish washer ? no well your car has alot of sensors that dont like water at all it sounds like the T.P.S got wet replace it you should be fine if you have a scaner you can watch it to see what the volts are
