91 Galant auto transmission problem

I have a base model 91 Mitsubishi Galant with auto trans. It has a sohc 2.0 liter engine with about 130,000 miles on it. The car is in good condition other than the transmission problems. I have tried to keep the maintenance up on the car over the 6 or 7 years that I have had it. I even kept the fluid and filter changed in the transmission according to the maintenance schedule in the owners manual, but it still went out. I ordered another transmission online awhile back and installed it myself. It turned out to be not all that hard of a job. I even change the filter before I added factory fluid to the recommended level, but when I started the car and went through the gear selection, nothing happened. I have the front of the car off the ground so that the wheels can spin freely, but they don't move in any gear including reverse. Also, the fluid does not go down or move at all when the car is in gear and the fluid is viewed through the fill hole. After I called and talked to the guy that I bought it from and his mechanic, they told me that I broke the pump when I put the torque converter in, because I probably pushed it in to far. They also told me that this was quit common with Mitsubishi transmission. I want to know if this is true and if it is possible for me to just replace the pump myself and about how much should this cost? Thanks, in advance for any help.

FIRST OF ALL DID YOU FIGURE IT OUT YET? IF NOT WHAT KIND OF ENGINE IS IN THE CAR? DOES IT HAVE OVER DRIVE OR NOT AND DOES IT LOCK UP LIKE A BAD SOLENOID? IF NONE OF THESE A YOUR CONDITION CHANCES ARE YOU HAVE A BAD PUMP GEAR OR A BAD PRESSURE SOLENOID IN THE VALVE BODY. THE SOLENOID WOULD BE THE FIRST PLACE I WOULD LOOK. IT IS THE MOST ACCESSABLE. UNFORTUNATLY GUYS LIKE YOU AND ME DON'T HAVE ACCESS TO TRANSMISSION INFO I JUST AHVE SOME EXPERIENCE WITH THESE.

ALSO SOME MITSUBISHI'S HAVE A 4SPD FUSE IN THE FUSE BLOCKUNDER THE DASH, CHECK THAT TO SEE IF IT IS OK.
IF IT IS PULL IT OUT AND TRY TO START IT AND PUT IT IN GEAR. THIS WILL PUT THE CAR IN LIMP MODE AND YOU SHOULD HAVE REVERSE AND 1 FORWARD GEAR(USUSALLY 3RD OR 2ND). IF NOTHING HAPPENS ITS YOUR PUMP AND THE TRANS HAS TO COME OUT AGAIN, YOU MAY BE
ABLE TO CHANGE IT IN YOUR DRIVEWAY DEPENDING ON YOUR SITUATION WATCH THE TEFLON RINGS WHEN YOU PULL IT OUT THOUGH THEY ARE TRICKY

No, I did not get it fixed yet. The engine is a 2.0 SOHC nonturbo four cylinder. It is a four speed automatic with overdrive. It does not lockup because it does not move or make a sound when it is put in any gear including reverse. While the car is in gear with the front-end off the ground you can spend the tires freely with you hand.

Does anyone know about how much the trans pump cost and where one can be found?

CHANCES ARE IT IS THE PUMP GEAR OR THE PUMP, HOWEVER THERE IS THE POSSIBILITY OF THE OUTDRIVE DIFFERENTIAL GEARS NOT MESHING. THAT CAN BE DEFIND BY SPINNING ONE WHEEL AND THE OTHER WHEEL WILL SPIN IN THE OPOSITE DIRECTION (WITH THE WHEELS UP OFF THE GROUND AND THE ENGINE OFF!) IF THIS DOES OCCUR THEN IT IS A PRESSURE PROBLEM. YOU CAN CONTACT TRANSCRAFTERS. COM, MITSUBISHI, ORTRANSTAR FOR PROBLEM PARTS.
MY SUGGETION TO YOU IS TO ALSO RENT A PRESSURE GAUGE AND CONNECT IT TO ONE OF THE OUTSIDE FITTINGS AND MAKE SURE THERE IS ZERO PRESSURE SO YOU DON'T WASTE YOUR TIME
