[tobaccogrower]

i can't complain!

it's been quite some time since i have had a problem with my rig!

i have the DTT 91%TC and racing VB. i have had the tsb 18-02-99 done about 2 years ago and it took care of the problem. now my TC is locking and unlocking under light throttle at low speed(35-40mph)it has also done this at highway speed,but only a few times. i have checked my fluid level and its ok. it's been about a year since a new transmission filter, so i dont think its that. any ideas? i will take the truck to go see MASSDIESEL in a few weeks when harvest is over and have him have a look at it. TIA... . james

TC lock/unlock

I had the same problem and after performing two different flashes on ECM and PCM, the local stealer replaced TPS under warranty and so far no problems. Good Luck
