Hey Brian, 2 more things
1. I misspoke about the flywheel, pressure plate, and disc. These will need to come from a 92 and up 3.9 or 5.2. The flywheel needs to be 143 Tooth? vs 130 tooth for the earlier version. (87-91) You need the larger flywheel for starter spacing. Both 3.9 and 5.2 are neutral balanced and the difference being the notches for the crank sensor will not apply to your TBI motor. The 3.7-4.7 flywheel is not compatible ..... The clutch disc has to be 10 spline to match the NV3500 transmission vs 23 spline? for the orig.
2. The 97-91 clutch slave cylinder can be used, but you need to slightly grind the mount of the slave cylinder to fit. FWIW I like the 87-91 style better. It has a bleeder, where as the 92 and up is a sealed system with no bleeder.
Look forward to hearing progress!!

I have a 93' Dakota LE purchased brand new, 5.2L, auto trans (46RH), 180K miles. I properly maintain my truck incl the transmission. The tranny has not given me a lick of trouble. Ralph is correct...take care of your crap and your crap will take care of you.

I took care of it for the time I've had it. I wasn't the first or the second owner. Not to mention there are brand new cars that fail before being bought. Sometimes it's just bad engineering that makes something bad. I know all too well about taking care of vehicles. One of my other cars is a 2006 Accord with 325,000 miles on the stock engine and automatic transmission.

No, you can't just use your GPS.
The ECU relies on the VSS for several items to maintain the proper air/fuel mixture while under load.
And despite what you keep hearing from folks who don't believe in maintenance, Dodge transmissions aren't junk.
What IS junk is expecting them to "just run" when they do require preventative maintenance ...
(A 46RH/RE will hold up very well against, say, a 4L80E or even an AODE/4R70W ... and they're not impossible to build and take care of yourself! But eh.)

Anything mechanical is going to require preventative maintenance, as Ralph alluded to. In your case, the previous owner must not have taken care of their vehicle. I'm in the same boat. My truck only has 68,000 original miles, but was neglected, sat for many years, and shifts into 'drive' harshly at times as a result. As for your truck and mine, they're in the hands of knowledgeable owners now.
Definitely not trying to gang up on you, just stating an observation. Good luck on your transmission swap!
