Hi,my name is mike and I will assist you with your question.
Is the vehicle setting any codes?
Was the transmission that you swapped with 2nd hand?
Customer: replied 4 years ago.

Hi. Yes I swapped with a second hand transmission. As for the codes I can't recall the numbers but I remember it had throttle position sensor, accelerator pedal position, oxygen sensor and cylinder 2 misfire.


 


I reset the ecu manually with the pedal and now the check engine light is gone.

Expert:  Mike Kelly replied 4 years ago.
Ok with the RPM's going to high,this is a indication that the valve body or the torque converter is causing the issue. The valve body might be loosing pressure or the torque converter might be slipping. This sounds like you may have gotten a bad transmission,but first the vehicle needs to be hooked to a transmission scan tool and test driven. This will monitor the converter,pressure readings,and the shift times.

Is it possible that my old valve body on my previous transmission can be used?


Because I've got a spare valve body and valve converter. I had it changed because of a burnt clutch pack

Yes this is what I would do if it were mine is reuse the old parts provided there is not metal debris located on them.
