high reving

[skter97]

was drivin my truck through town last nite when i went to give it some gas and all it did was rev up real high and then it slammed into gear, could this be the solenoid going out, or what could this be guys... it did it three times and hasnt done it since.

Check your tranny fluid. If it is good, add maybe a half a quart. It hasn't happened to me, but I have heard of it happening to other guys. Sometimes their tranny fluid is low, and they top off and it's fine. Others have to add just a bit more into it to make it go away. Also, these trucks have adaptive learning. If you take it easy a lot, then want to hot rod it, the TCM get's confused on what to do. Gun it hard from time to time to avoid this if your fluids are good. Good luck

Ill go out and check the fluid now, what type does it take i forgot lol lol.. It may have been the adaptive learning because all evening i was babying the truck. Ill keep and eye on it, do you have any experience with the suncoast solenoid, i wonder if its worth it.Its suppose the hold the pressure better, it might be a must with the 310 tune.

The type is Mercon SP. Don't use any other.

I have heard of the trucks doing this stock as well, so it probably is a fluid issue...not the Spartan tranny tuning. It has happened to me before when I was going around a curve. Let out of it and when I hit the pedal it reved slightly, and then caught the gear

My truck has been doing the rev and bang after coasting for some time now, but yesterday it happened a little different. I got on it pretty hard off a stop light and all heck broke loose. It started shuttering between gears. I let off and it went ahead and shifted.
