No kidding, I wouldn’t waste my time with a regular rex 5MT (got one now), plus you’ll have to change gear ratios or put your old R&P in. Try to find the larger Forester 5-speed or throw some RA gears in a rex tranny before installation.
Also other notes, if you do go rex DO NOT get an 05’ rex tranny or you’ll have to deal with different shafts and seals (again, like I did
). Also your existing VSS will bolt right up no problems, although I think the other connectors may need to be rewired...
Good luck man…
