42RE Guidance Needed

Looking at picking up a spare trans to rebuild so I can have it in my back pocket when mine decides to take a dump. Need some help with this rebuild kit:

Dodge Chrysler Jeep A500 40RH 42RH 44RE Transmission Deluxe Rebuild Kit 1989-ON

Didn't know there were two different widths on the band for a 42RE? Apparently there is a 1.375" or a 1.6" wide band.

Also, thoughts on getting a slight upgrade with a torque converter? Found a Hughes Performance Towing TC on Summit that was used for good low end grunt.

Any input on these topics would be appreciated.

Its been awhile since I looked and Im pretty sure with the 42's there shouldnt be a difference in whichever one you used but the correct one would be the 1.6" The smaller band was carried over from the TF904/A500 era.

Thanks. I don't have a disassembled 42RE I can look at, but from pictures I've seen, it looks like it would be a 1.6".

Any input on the torque converter?

Bringing this back to the top because I finally got an answer on this question.

Late model 42REs will have the wide (1.6") band and early model 42REs will have the narrow (1.375") band. I believe the cut off year is 1994.

Unless there are drums out there that are different the band width shouldn't matter. The drums were all the same size diameter and width. Meaning if you have the smaller band you can install the larger band. It would be better to have the larger band but don't go the other way.

There are two different band drum diameters. A 6" diameter drum which I have found as late as 1993 and a 6-1/4" drum which I have found as early as 1989. Go figure.

Not only that, but both drums came in two bushing configurations. A single wide bushing or two narrow bushings meaning that the drum tower changes at the same time.

And, of course, the drums were machined for 3, 4, or 5 frictions, for a total of 12 different band drums that I have found in 42RL/42RE/44RE transmissions.

Only easy part is they are all the same length when measured from thrust washer to end of drum (band surfaces are SOMETIMES different widths between 3-/4- and 5-friction drums).
