No down shift in Tow/haul and wacky TC

[Big Block 88]

Hey Mike I was sayin in another thread that our LB7 is having some strange things going on. It shifts totally fine but it will not down shift in tow haul, and the TC is locking and unlocking alot.

The truck averages over 30K GCWR most of the time for the last 200K miles and has only been limped one time, my fault I had the temp gauge pegged tell it limped. Fluid and filter changed the same week, it did smell terrible

Thanks

Got to bump this to the top, the truck is NOT downshifting or holding gear when the throttle is lifted it's killin the brakes on the truck and trailer. Truck had smoke rolling out of the front wheels after coming down from estes park. I can lock the shifter in 2nd but I have never had to do that before.

Sorry for the delay Mike the truck is in San Antonio right now once it gets back this weekend I will call you after I drive it again, so I have my ducks in a row.

Truck didn't make it back from TX blew a cooler line and cooked it, is what I gather from the phone call. Looks like it is getting rebuilt at a dealer down there. Not bad though well over 200K miles under extreme loads is not to shabby for a stock alli.

Don't know yet they won't veen work on it tell the begining of next week. It would cost to much to have it towed up here to KS so the truck is being left behind with the driver, and the LBZ is headed down to get the 6 horse trailer
