|Response one(john emerick): possibilty of clutch packs reinstalled incorrectly else if works "manually selecting gears" then check valve body components e.g. edges of valves and if valve body is PERFECTLY flat especially towards center section.|
response 2 (tony):if coolant has entered the transmisson clutch packs and bands will have absorbed the ethyl glycol and changed their "lock/binding" qaulities, sorry bud but time for a rebuild:(
