Hey guys I have a raptor stage 3 4l60E tranny. It has less than 1500 miles on it. i drive like a grandma on the street. I have been to the track 3 times. I recenlty went to the drag strip and found that my tranny wont shift into 2nd gear under a full throttle acceleration. it just bounces off the rev limiter. Could i have blown the tranny already? Any help would be great thanks

Well its possible but just as likley to be some tuning or sensor issue, How do the part throttle shifts feel? You should possibly data logg it and see if the shift is being comanded.

 

The part throttle shift feel Alright. They are not to soft nor firm. It shifts into all the other gear great driving under normal conditions and WOT! I Ran the tts data master software on my 2nd run down the track. I looked over the Data it looked ok to me but I dont really know what to look for. Is there a Data logging program You reccomend?
Thanks
Tom

 

That could be shift solenoid A unable to vent. You could check the inlet, clean it then try swapping them, it's on the driver's side rear of the vb. If you swap them, you could lose your 2-3 but at least you'll know what the problem is.

Replacements are cheap enough.
