Thanks. No a rear seal will not cause running problems and generally only an oil leak. Cold start or cold running problems could one of several things.You could easily have one or 2 injectors not seating all the way and slowly dripping overnight and will cause rough run, possible hard start, miss and /or hesistion when cold. A fuel pressure reading is required to check this. As far as rear seal, the trans has to come out then the flywheel off then the seal. A special tool should be used but.. you can tap in with hammer if very careful.
