auto trans tcu trouble shooting

[mikeu1995]

Today about after 5 minutes of driving I stopped put the car in park with out shutting off the car I put it back in drive I didn't feel the car engage into drive it took a few seconds. so I hit the gas the car moves slowly but then catches gear fine. once it shifted into second it felt like it slipped out of gear a few seconds later as if it went into neutral. The car wouldn't engage into any other gear after this happened. I pulled over checked fluid level looks ok no leaks.
after turning the car off and then on it goes into gear but the same happens again after about a half a block.

I checked the TCU codes and it flashed 63 = short circuited torque reduction execution line
I removed the TCU to check for physical damage and it looks fine no cap leak or burnt board.
so i reinstalled the tcu to double check and it still does the same thing. but now when i go to check for codes it gives me constant short pulses which = to it being ok.
Any help will be greatly appreciated.

Sounds like a solenoid going bad. I had a simalar issue with mine but it would down shift hard and then on take off it didn't change out. I pulled over and turned off the car and it drove fine. Go have the fuild and filter changed and see what outcome you get. I wouldn't recommend power flushing because Mitsubishi don't recommend power flushing of any fuilds on own cars. Good luck on founding out what's going bro.

I should have noted that the trans oil and filter have been changed. I also did a master rebuild on trans. I installed it drove fine for a good 2 miles when I got home put in nuetral to check the oil level the problem started to happen. I don't think i have a mechanical problem it deffinatly is a electrical problem. One of the solenoids did read .400 kohm on the multi meter the other 2 read 24 ohms which is odd.

All of them are suppose to read 24 anything less than that means it'sbad. If you change them just change all of them at one time and that should correct your problem.

UPDATE: So i finally replaced the solenoids with a brand new kit I purchased from IPT. The car drove fine shifted well for about 10 minutes of driving. Then the same problem I was having emerged again. The trans goes in and out of drive and then goes in to neutral mode. I turn off the car and start it back up shift into gear and it sticks but than after about 3 minutes of driving it slips out of gears again. Has anybody had this issue and if so what did you do to fix it ?

New Update, Car is back on the road! Its been cold and haven't had much time to mess the car. The problem was dirty oil and a clogged filter. Even though I put a new oil/filter after the rebuild, I installed the torque converter that i did not covered up nor did I replace the trans fluid from before the install. So my problem was from small/ground up pieces of fiction plate material clogging up the filter which caused pressure issues inside the valve body/solenoid making the care shift in and out of gear. I changed the oil 3 times and filter 2. The last oil change I added B&M trick shift after that my problem was sloved.

Question: Does anyone have an auto with a shift kit? and how hard is it suppose to shift back into 1st gear?
