torqshift tranny questions

[cowboyupamrka]

Okay i drove my roommates truck, its not mine, and before it gets totally warmed up the transmission has problems. after it warms up it is fine. but i drove it after she got home and it did this:

first gear and then it gets stuck and holds there like it wont shift out of first. wont go up in rpms even if you hit the pedal harder. finally after a few seconds it shifts into second then does it again, finally goes into third then it is fine for the rest of the gears. does this for a few minutes of stop and go and then it is fine. Shifts regularly and you could never tell there was a problem.

I'm by no means an expert, but are the fluid level ok? Scheduled tranny service been done?

If nothing else here's a for you.

Mine shifts funny when it is cold also, not really like that but it seems to want to slip out of gear and into neutral unless I am barely over idle. If it is warmed up or if I just start and let the tranny temp touch the gauge it is just fine.

The 6.0L trucks hold themselves back on power until they warm up. This is to help the transmission live longer. I have had customers tell me exactly what your saying and it be just that. The truck is holding back power until the trans is warm. This lack of power does make the trans feel weird. I hope this is what you have experienced. Take it to the shop to be safe. They will probably need her to leave it over night to cool, but atleast you will know if its normal or not. Thats kind of a hard thing to diagnose thru the keyboard lol. Good luck

thanks for the replies, i will see what i can figure out. but yes the fluid is full, i did check on that. hopefully it is just what you were saying about it waiting til the truck is warmed up. we will see

I had similar issues and mine was a bad injector. You had to let the motor warm up and the injector started working. But like the last guy said it really isn't the tranny its the motor.

Mine hates it when it is cold. Winds out the gears then slams into gear. So, I just baby it till it warms up, then it runs GREAT!!

Also, does he have a tune on it? I notice it more when in a tune not stock.

Nope no tune on this truck (unfortunatly). I am his roommate by the way the truck is mine and its not the one in my sig. I got it fixed though. I took it in and go the newest updates and now it runs like a dream. Still lags a little bit if its not warmed up but I have been told that its just a protection for the transmission. It used to sound really bad when i started it in the morning and now it purrs like a lovely diesel kitten.
