whe the car runs up to 70 or 75 m/h my trannys runs normal with no problems . but when i increase it to 80 to 85 m/h. rpm goes to wild/ transmission lost control gear shifted to neutral.need to slow down before it will shift to gear.
is this electronically or mechanicaly problem and where to look.
Sounds electronic, have you checked for any memory codes?
All auto trannys have a shift knotdown cable and the shift on side of tranny could have been knotted off of its alinemant marks if you will take cable lose use a flash light and make sure your alinement marks are lined !
There is a slot in the leaver on side of tranny that a bolt with ajustment screws keep in place behind are the alinement marks !
