Torque converter, 48re

[BTiner]

When coming down a 6% grade ( with a 11,500lb. trailer), I put the trammy into the towing mode and shiffed into 2nd gear. Around 2500 rpm the converter wouldn't' stay locked up. It would shift back and forth. A week later I tried it again and the same thing happened. When I got back home I took the truck to the dealer and they hooked up the computer to it and no codes came up. They test drove the truck and nothing happened. Next week I'm taking the truck back to the dealer with the trailer hooked up. Since I'm in Texas it is hard to fine a steep long hill. Also, with the trailer hooked up and starting from first gear I'm setting a light shudder from the converter. Has anyone experience any of these problems?? I had 3750 miles on the truck before I pulled the trailer.

I don"t think you will get a stock set up to stay lock up with out a commander. Only 3rd and 4th,the stock TC has a program dis-engagement . and WOT.
