My LCI REX is closing in on 30K and started looking into replacing the transmission fluid. Stumbled upon this
really good DIY by
evilchargerfan. The only problem is it was done on a early model car that still had a fill plug.
I've read you can fill using the breather vent at the rear of the tranny, but with the REX it's a tight squeeze to access the vent. Has anyone been able to do this service on a REX without removing the right-side output shaft?
