Hey, I'm a mechanic but have little experience with swapping from one vehicle to another, that said, I have a stock 1994 4Runner with 3.0 v6 and A340H transmission 287,000 miles, transmission is trashed, hard parts worn out, i have a A340F from a 2000 4Runner and a transfer case from a 1994 T100 it all fits together fine my problem is the output shaft speed sensor the 2000 has a 4 prong non-magnet ring on the output shaft, the 1994 has an aluminum ring with a magnet, different speed sensors, has anybody tried this? any suggestions? , Just bought a new ECM for it because it was bad too.
