Yes, my 1992 Dakota shop manual states that the 42RH is used with the 3.9L and the 46RH is used with the 5.2L. The difference in the transmissions is the first and seconed gear ratios.
That is exactly what you said.
the 500 and the 518 are NOT the same part. Nor is the only difference the first and second gear ratio.
I did not say it was the ONLY difference. So I guess in hindsight I should have said ONE of the differences from a driving usage and street rod retrofit perspective, rather then a strictly technical point of view, that might or might not be important for the original poster.
So you are right,......I will not be posting on this subject again and will be very hesitant to post or participate on other then my build thread in the future.
