ok so I'm driving home from work last night and turned my check engine light on. codes are po735 5th gear ratio and po843 solenoid c. I was passing a tractor trailer and had to walk on her next thing I know there's a loud bang and I stuck in 4th. I know I limped it but in your guys experience what should I do? I cleared codes and she seemed to drive all right today. Forgot to mention bullydog on stage 3 Extreme I usually run on stage 2 performance . thought i would try it on 3 probably a costly error. what do you figure? Any idea how long before allison is RIP
oh ya 2003 duramax 2500 hd just over 113000 miles:cool:

Sounds like a limp to me.
Load the stage 2 or even the stage 1 and you'll be fine for a while. But start saving and reading up on after market tranny options. When towing you might even want to go back to stock.

thanks wanadmxsub thats what I figured I went back to stock. Funny how you read about stuff happening after you do something dumb. Got a tranny coming, I'm not use to walking I drive a DMAX
