Hello Fellow MS Owners! Long time, no post. Still ridin' in my '01 XS but have been having an issue lately that has me perplexed to say the least. It seems ever since I had a local dealer do their suggested transmission service, my truck will intermittently slip out of gear. So far these are the only circumstances I've noticed as any kind of pattern: - It seems to happen only when the truck is cold/has been sitting a while
- It can happen when I back out of my garage or a parking space and try to go from R to D
- It has also happened when trying to accelerate from a stop or even while rolling over a bumpy road
- It does not seem to happen at all once I've been driving a while and the truck is warmed up
Any ideas or suggestions on what this might be before I take my ride back into the dealer to have it checked out? Thanks all! Macadamia

Does it rev up then settle down? Could be going in and out of overdrive. How is your fluid level? Clay

Sorry for the late response: I did check the fluid level and it looked good. And then it really hadn't done it again for days (coincidentally the weather has been much warmer here in the Tampa Bay Florida area), but still seems to kinda do it when I go over rough terrain or make a quick stop and go at a light or stop sign. Any clues?

Good news (I hope) - had an unseasonably cool morning today and did not experience the "slippage" I reported previously. Not sure if this is something that worked its way out or what. Going to still have the dealer check it out next oil change regardless. Thanks cwic for your reply and advice.

See what they think at the shop without offering up any suggestions, just be detailed when you describe it.

More good news, I have not had the slippage problem in many days. Hoping whatever it was corrected itself. Could it have really been the cool weather we were having here in the Tampa Bay area?!? Weird. Will post again when the dealer checks it out, but am now not in any rush.

Was there any reason that the dealership would have disconnected the battery?

Hello again, finally had my MS into a more trust-worthy dealer for an oil change and asked them to check my tranny. They couldn't detect anything wrong and just told me to "keep an eye on it." So far, so good. The service guy suggested that maybe a tiny piece of debris was temporarily clogging something and has since worked its way out? Oh, and they also tightened up my "AFTER MARKET" belts the previous dealer put on for me - turns out I wasn't paying close enough attention and those yahoos use NAPA parts instead of genuine Mitsu parts. Suffice it to say I will NOT be going back there. P.S. No battery disconnect recently, no.

Good to hear, I wish mine would stop going in and out of OD while on even the slightest decline at freeway speeds. Clay

Just a thought, but I would start saving for a new toque converter. It sounds like this one is worn pretty good. Also you may check the throttle linkage to the transmission. Not sure what they call it, but this is responsible for downshifting the transmission to pass. There may be slightly too much tension on this cable. It does not make sense that this happens when you let off of the gas, but it makes sense if you are going up a hill and trying to keep the same speed by pressing on the gas pedal.. How long has it been since you changed the tranny fluid?

Am having the same problem with my 02 MS. Took it into the dealer and had the trans flushed. Described the problem and the dealer has had it twice now and they can't replicate the problem. Fear the next step will be them tearing it down.
Would there be any error codes showing up for this type of problem?

Talked with the service rep today. While test driving the vehicle today they stopped at a stop sign and when they attempted to go they had to rev the engine up to about 6k rpm before it kicked int. They had the computer plugged in and they did not see any faults. Current thought is the front transmission pump is losing prime. Any one ever here of this?
Would this also cause the problem where it will go in to reverse and then not go into drive? This typically happens after it has been sitting over night.

I have seen this on the Diamante's where a wave spring breaks and is ingested by the pump which then does all kinds of funky things. I would check the element application chart and monitor pressure on those in use at the time the fault happens.

Thanks, took it to a local independent trans tech shop and they asked if I drove it to the shop because they could not get to go into gear. They finally got it into the shop and dropped the pan and found crud (shavings) and the filter was pretty bad. I had the vehicle flushed about 3 weeks ago at the dealer and I am now finding out they did not drop the pan or replace the filter when they did the $160 trans flush.
Also found out the when they do a trans cooler type of flush that there is a real good chance of flushing crud into the pan and then into the filter. Unlike the engine oil filter which is behind the oil pump and has a by pass valve, the trans filter is in front and if it is clogged with this crud it will prevent fluid from getting to the trans....
Looks like I will have to do battle with my extended service contract company - wish me luck.
BTW this is an 02 Sport with 80K.
