I installed a new MAP sensor and had a minor problem with not getting line preassure at low throttle input talked with a tech and thought I fixed the issue ,, now the trans is locked up in drive ,, I cant get reverse and the truck even rolls foward in park ?????

I talked again with tech and they suggested sending the cal file and datalog ,, when I tred it I found out that all the saved files for calibration were gone from the computer and it wont record the dattalog either ...

I'll check all my connections but Im stuck ,, the truck wont move but foward and nothing changed on the TCU wont help ..

Any ideas ???????

I was looking at the truck last night after work and decided to disconnect the harnesses from the transmission to see what happends ,, the truck still is locked in drive ,, so one of the valves in the trans itself is stuck open ...

On a brighter note I did find the missing files ,,, The owner of the truck put them all in a specific file in the harddrive that I forgot about so everything still here ...

What transmission is this ? It could be a clutch pack melted together.
