SSplaytoy Posted January 19, 2005 Report Posted January 19, 2005 Sometimes when I punch the gas from a stop it won't shift outta first. It keeps redlining until I let off the gas. WTF?
edessa Posted January 19, 2005 Report Posted January 19, 2005 Mine did that twice the other day. Hase not done it after that. I got 78 miles left till warrenty expires. Think I'll take it in, in the morning.
Jonmalibuss Posted January 19, 2005 Report Posted January 19, 2005 I had the same problem it is a warranty issue they have had problems with the valves sticking I think it's a clerance issue because it only did this when it was cold. They replaced the valve body and I havn't had a problem since!
Dr Mike Posted January 19, 2005 Report Posted January 19, 2005 Sometimes when I punch the gas from a stop it won't shift outta first. It keeps redlining until I let off the gas. WTF? <{POST_SNAPBACK}> There's a TSB out on the 4L65E Trans in 2500 series, but our truck has same tranny. Problem is called Trans slipping between 1 and 2 followed by harsh shift Although nothing shows up for SS, shop foreman ordered the updated Servo and had replaced in November. Working like a charm ever since...

Xero Posted January 19, 2005 Report Posted January 19, 2005 will the zippy shift kit fix this problem? cause i had it happening before and i have the shift kit but with that kit will it happen again?
SSplaytoy Posted January 20, 2005 Author Report Posted January 20, 2005 I have the Trans-Go shift kit, aluminum accumulator piston, and vette servo. They wont take out these parts will they?

The dealer will most likely not look for modified/aftermarket parts to reinstall them they will more than likely pull the valve body and replace it with a new one along with the spacer plate. If you find a dealer that is willing to keep the parts from the shift kit and install in the new valve body you may need to provide them with the instructions so they know exactly what they need to keep/swap to the new valve body.
SSplaytoy Posted January 20, 2005 Author Report Posted January 20, 2005 I will see if a guy who works at a dealership I know will do it.
lucky7_93021 Posted March 12, 2006 Report Posted March 12, 2006 When they replace the valve body, would they do anything to effect the PCM programing? If so I can swap for the OEM when I bring it in.

faceliftedss Posted March 13, 2006 Report Posted March 13, 2006 my friend had this problem in her caddy and it ended up being a shift sensor inside the tranny. after the car would heat up the sensor would malfunction. it may not be the case here but this is the same thing her's did just before it went out.
lucky7_93021 Posted March 13, 2006 Report Posted March 13, 2006 sounds good ill put the stock one back in. i dont think it's a heat thing becuase this happens most in the mornings when it's cold. thanks guys!

There for that valve body is junk don't let them tell you that they are going to clean it and put it back in because the problem will still be there.
lucky7_93021 Posted March 13, 2006 Report Posted March 13, 2006 So if this is a TSB would it be covered even if I am out of warrenty? If not, what would it cost to have this done at the dealer? I have a shift kit that I've yet to install... would I be better off having the trans shop fix this when they put in the shift kit? Thanks for all the great help as usual!

A TSB will increase your chances of getting it warrentied, but does not require them to warrenty it.
