91 Montero Tech Info Request

Hey fellas,

I sold my beloved 91 Montero to a good friend, and a year or so later the trans started slipping. I can't imagine why... it only has 286k on the ticker, many of which are hard, loaded down, rock climbing, water crossing, snow blasting, 4-wheels off the ground hill jumping, stuck in the mud miles, and I am pretty sure the guy who owned it before me towed a bigass boat. Anyway, we threw a used trans in it, everything is good, all the gears are there, shifts smoothly, but the darn thing will not drop into 1st automatically after a stop, wants to start out in second unless you manually shift into 1st, or pop it into reverse or park then back to D.

Kind of embarrased seeing as though I was a master Mits tech at a dealership for 18 years. But I've been out of it for a while, and the truth is we never ever saw any problems with these transmissions. They are rock freakin solid!

Any ideas? Links to other threads? Links to other forums? Man I wish I still had access to the Mitsubishi factory tech line!

I'm in graduate school and crazy busy. I only did a quick search and I'm throwing out a rather hasty thread here so my apologies if I missed something obvious that would answer my questions.

Also, I have owned and worked on Mitsubishi's for over 20 years and know a few things so if I can ever help anyone with tech questions feel free to contact me:

Not really here
It honestly sounds like an electrical issue. If it was mine, I'd say that someone forgot to hook something up. or left the transmission switch in the hold position. What year monty did the transmission come out of? If it came out of a later model one, you may need to hook a transmission mode selector switch to it. Hope you figure it out.

91 did not come with a hold function... But that said, I wonder if a gen II transmission was somehow accidentally used and without the correct transmission settings the transmission thinks it should be in 'hold' mode?

Also/alternatively was the tranny fluid replaced when you did the swap? I assume the correct fluid went in?

4x4 wire dot com has a good mitsu tech forum to check out.
Mitsubishi links dot com has PDFs of many of the FSM's including my old 89 FSM which was scanned for prosperity.:ylsmoke:
