A-518 and 46RH find

Same transmission. There are 2 series transmissions. A 46RH (hydraulic control) and a 46RE (electronic control ie computer) change over was mid 90s. Look for a big electrical connector to indicate a 46RE.

Change was 96, I recall.

A518 and 46RH are basically exactly the same. 518 is hydraulically commanded. RH, the H stands for Hydraulic. Guess what? Hydraulically controlled. All of these feature lock up convertors. As Valiant said, 96 ish they went RE. E is Electronically controlled. If they are 2WD, snag em!!! Hard to find! Even if they're 4WD, still have value.

Yes, 96-I had a 95 Dakota with a 46RH.

I understand that they went to electronic control around 95ish but why do ther refer to one as a 518 and the other as a 46RH when both are 1994 vehicles ? It could be possible that the van plant still used the old 518 jargon I suppose

Old software, early build...just couldn't be bothered to change it?
