4R70w shifting issues
A lot of the time at stops my truck will studder and act like it will die and has died once. On the road driving it will sometimes shift a little hard but other than that it is fine on the road. i thought it was something else until I read your thread but the intake is fine filter is fine and just had the fuel filter replaced too. If you think it might be something else let me know but it sounds a lot like what you had.
Thanks

I think a occasional shudder is sorta common with these. For em the test was easy to see if the TC was locking up. Start the truck and with foot on brake put it in 2nd gear. (1st and reverse has a by pass circuit that eliminates the TC control circuit .
So the other day I went and got my duals put on my truck and now the studder has disappeared. I don't know if there was a problem with my old muffler but so far I have not seen it come back. I really like it but does anyone on here know why this might have happened?
Hi Everyone,
I have a quick question.
What does TCC stand for? I was trying to figure it out from the posts, but the only thing I could come up with was Torque Converter Control??
Also, what is the TCC's function?
Thanks

You got it right.
The converter is designed with a lockup feature to overcome fluid slip, making the drive at that point a sold link during engagement.
Improves fuel mileage, reduces trans heat.
The TCC is the electric part of the lockup control in the trans and commanded by the computer.
