working on a friends car, it starts but when you put it in any gear it does not move, rpms seems to drop a little like it engaged,also when its cold it should be above the fill line which it is, when hot the level drops down a bit 1/2 inch? not as much as in a working trans in other cars which drop about 1 inch down, no codes..fuses seem fine, a/t trans relay good..trying to work on this without all the scanners and such..old school way..looked at flexplate and converter attached..nothing broken there..trans select switch ohmed out ok ..any thoughts???
