Sorry, pull it out. Can't fix it in the car......
Will the transmission explode if my son drives it like it is for a while....funds are low right now and he really needs his car to get back and forth to work. We have 2 cores that I can rebuild later (summer) but we need to get all the parts to do it.
the transmission was never useed by us before the shiftkit install.
