Transmission shifting issue? I think.

I am not sure if this an issue or not but intermittently going up long or short grades the tranny/rpm at 70mph moves from 2250 to 2500ish. It does not feel or sound like a shift. Its kinda worrying me. Also when you put it into drive from reverse there is sometime a brief pause then it engages. I hope this is normal for these transmissions.

Thanks for the replys.

The change in RPM is the lock up torque converter disengaging.

The reverse pause is a common problem with the 6.0 TS tranny that there is no fix for and will not hurt the tranny as long as you do not rev the motor at high RPM while it is trying to make up it's mind what to do.

Great thanks for the info. Would it stop locking/unlocking while in tow mode?

No, it won't, but it will be different in tow/haul.

Can you describe how different? And is it hard on any thing?

In T/H mode I believe the converter takes longer to lock up then in normal mode.

It is not hard on anything. The tranny is programmed to respond to load conditions.
