John Wood vs. Brian's Truck Stop vs. ?

[Diesel Monkey]

I had a good local shop build a transmission to stand up to turbo, Tony Wildman chip and injectors. Seems rugged as anything, but when at light throttle going up hill, it wants to jump past second and lugs the motor. The local shop says everyting is just perfect, but it does lug and starts to pour black smoke. I usually push the OD button or pull it down into second and the motor spins up to 2200 and stops smoking. Is this a programming problem or a valve body (or both?) Would a John Wood valve body help?

I can't really help but to awnser the question I would go John Wood over BTS. Guess there have been a few BTS tranny's that have been rebuilt by JW but no JW tranny rebuilt by BTS. Also to the parts out of the BTS aren't like the parts in the JW units.

I suspected the programming, is this something that is coded into the Tony Wildman chip or does the transmission have a ECU in need of modification?

Diesel, make some notes on it for me and send me the chip back and I will make some changes in the shift pattern.

Funny you mention that when mine is in stock it does the same exact thing and I mean exactly the same thing. Maybe mine is built to, I havent had a chance to check. I also drive an ambulance at times that acts similar.

Thanks Tony. When there are multiple vendors, and a problem, it is difficult to really find the cause. I really appreciate the help Tony. I will get some notes together this week.
