a500 - 42rh trany help

I have a 1991 Dodge Ram 50 automatic 2 wheel drive truck with the A500
type 42rh trany in it. It has problems shifting up after you start it
(once it shifts threw all the gears it works fine) and the reverse band
is bad, so i cant back up now. I am told i need to have it rebuilt and
evewhere i check they want $1500 to $2000 to fix it and that is more
then i paid for the truck! I am checking around in salvage yards trying
to find a replacement trany and haveing a very difficult time because
it seems that the dodge ram 50 is pretty rare in my area.

Can someone tell me what other vehicals i could be asking about that
have this/compatible trany or if you have any other ideas?

Thanks!

 

IT'S not a ram 50 thats the small Mitsubishi truck. Try looking at Ram
1500/ Ram van 1500 / Dakota. As far as reverse, drop the pan & check the
strut-bar between the band & adjuster it may be broken or if you are lucky
maybe the band is way out of adjustment & the strut fell out If the end of
the band is broken it's rebuild time. The A500 came out in 1989? is a
varaient of the earlier A904/999 with an added overdrive, USED in many of
the rear wheel drive vehicles. Be aware when looking Jeeps used some
oddball transmissions.

 

Ever try pulling the pan and seeing what's going on in there? You
might have a varnished up valve body for all you know. Sounds like
someone's never done any trans maintenance, and your reverse band is
either way too loose, or the anchor's cracked.
