what is the rpo code? on a sticker in the glove box(MG5/MY2/M50)
this is what alldata shows for that option trans
If the trans is rebuildable and you are doing the labor you might get a price on the cost(parts).
4 hrs to remove and replace(so you know) and about 5-6 extra to rebuild.
those transmissions are automatic, you said it was a manual and the rpo agrees.
they call it a 5 Speed, Hydramatic (MG5/MY2/M50) the rpo codes identify it.
