i have one in a mustang and it shifts great 1-2 but when it shifts 2-3 it slips bad going into gear once in gear it is fine. it will rev up almost 2ooo rpm before it engages.
I know nothing about it but I am mechanically inclined I can build motors and I am a forklift mechanic.
I was told it could be a bad servo piston or seal.
thanks for your time and thoughts
i have changed fluid and screen and then i did try the ole lucas treatment
How it reverse? Most likely there's some direct clutch or slip ring concerns. Pull the pan and look for trash in the fluid. You could do an air check but if this is the original tranny, just pull it down and see what you have. You've ordered my video which will show the things to look for.
