Let me get this straight, you are doing all this work, and you are female? That is pretty damned cool... <img src="/forums/images/graemlins/kewl.gif" alt="" />

As for the earier post from MBrannon, I think he was talking about having the tranny in HOLD mode. That's the switch in your center console that says something like A/T Mode.

There should be a switch on your center console. Is it possible that switch got bumped? Mine did once and I thought my tranny was going.

No its not skipping 1st gear and the indicator light isn't on.

We have seen a lot of funny stuff when not using genuine Mitsu atf on this tranny. The leak at the back end of the tranny is not too bad to get at. Remove the tcase and adapter, and the seal is very accesible. The adapter should be dry.

You should read the error codes. Download the factory manual from mitsubishilinks.com, courtesy of MontyMcV. It covers the 92-96 models, and should list the tranny codes and how to read them.

We rarely have the ladies come to visit, and even more rarely have on who wrenches herself. Welcome aboard. We could use the good influence...

Thanks for the welcome.
I've already got the fsm and the 6g72 manual- I used them to rebuild the engine.
I haven't gotten any codes at all from the transmission its like it wants to be elusive - if I had a code, at least I'd have a starting point.

Took her out this morning I could 35mph in 2 but only 20mph in D. At least until it warmed up - then off she went with no problems. Wondering if the AT temp sensor is functioning right.

This my very first rebuild! The most I've ever done before was replace a lower intake manifold gasket on a 98 b4000 and replaced a cv boot on a 4wd 95 blazer with abs. So this is a huge learning experience and frankly I don't know squat. I've been haunting this forum since last Sept. when I started this project and just recently joined. So thank you everyone for all your previous posts.

Well I was almost excited! The "A/T" dash light finally started flashed at me - then quit so she didn't hold the code. NUTS!!!

Double Nuts! According to the FSM - its the "Oil Temp Warning Lamp" that flashes for Transmission trouble codes. Darn it!

Wonder why the "A/T" light was flashing then?? more research- grrrr

The a/t light IS the oil temp warning light. The a/t light fires up when the oil temp goes over some astronomical number like 273*F, and flashes for codes on the electronic shifted a/t's. Lay your hands on a gauge that reads high enough and test the a/t pressures. There's two taps on the dside of the tranny toward the back for line pressure and regulated pressure. I've never been into the ebox, but I bet the problem is with one of the duty cycle solenoids that regulate the pressures in the hydraulic circuits under tcu control. They tend to leak with age. Pretty cheap repair and can be done in the truck by dropping the pan. The hydraulic circuits are relatively failure free on this tranny, as they are almost identical to the pure hydraulic model, a very durable unit.

Aamco is a bad choice for transmission work, but they give a free diagnosis, and see enough trannies with problems to give you a fair probability of a good diagnosis.

I've found it to be a bad idea to flush an a/t. Usually causes more problems than it fixes.

LOL, yea I found that out - that the A/T and oil temp were one in the same.

However, since it flashed at startup - i doubt very highly that the oil temp could have got that high within the first minute- the engine didn't even get above the cold mark yet.

OK - I found the hydralic and line pressure tests in the fsm.
it says to test pressure at each rpm but it only lists idle and stall.
Does stall mean at shut off? or am I suppose to stall my engine somehow?

In this context, "stall" means to put it in gear, lock the brakes and ebrake, and apply all the throttle you can without the truck moving. This generates max hydraulic pressure. The term refers to stalling the torque converter, not the engine.

You still have a very specific problem that was already pointed out but you haven't addressed - you have used the wrong transmission fluid. If you're having a problem with the transmission and you know of something that is definitely wrong, fix it before you move on with further diagnosis. You NEED to have the correct Mitsu Diamond SP transmission fluid in there - the same fluid is sometimes available at Hyundai dealerships for less money than what a Mitsu dealer charges, since Hyundai used Mitsu trannys in some of their vehicles. Wherever you get it, you need to change as much of the fluid as you can - a simple drain and refill will only change about 2/3 of the total fluid volume due to fluid remaining in the torque converter and transmission fluid cooler. There is a process for doing a trans fluid flush that involves removing the return line from the transmission cooler and running the engnine to pump all the old fluid out - I think there was a post here on the forum about how to do it, a search should be able to locate it. That procedure will remove more of the incorrect fluid than just a drain and refill will accomplish.
