PING Gary.. TCC question
 

'88 K2500, 700-r4. Is it normal for the tcc to disengage at zero
throttle? my truck does it and it drives me nuts esp. if I am
following someone, the TCC unlocks when I let off the gas and locks
back up when I press on the gas. it's done this for at least as long
as this trans has been in the truck (2 years now, I think) but it's
really really starting to annoy the hell out of me.

TIA,
Bret

Yes, at least for some of the other trannies from GM... Keeps the
engine from excessively braking the vehicle (an economy trick,
actually)
