Hi guys I'm stumped and this is my last resort now I have a 99 Cherokee sport and the trans went out so I replaced it and for some reason now it still will now work at all. Nothing works at all, I put it in drive, or reverse and nothing. The fluid is full. So I have no idea I'm stumped so can someone tell me what I'm missing

 

So I swapped out a bad trans and now my new trans will not work and idk why. I put it in gear and I get nothing. The transfer case is fine I know that but I really can't think of any reason why it would not be working..... need a lil help

 

Transfer case in neutral ?

 

No I checked that already

 

Do post #23 in the link below. It will tell you if there could be a problem with the torque converter or trans pump.

Its throwing a po743 code for the torque converter so I changed it and it's still not working

 

Could be a few other causes:

Common Problems That Trigger the P0743 Code
-Defective Torque Converter Lockup Solenoid
-Defective Engine Coolant Temperature Sensor
-Defective Torque Converter Clutch
-Defective Valve Body
-Dirty transmission fluid that restricts the hydraulic passages

 

Please explain, "trans will not work". That could mean a lot of things.

 

All I can suggest is that you check your work. What was the problem with your old transmission?

 

I dropped it back down and found the problem. I my old torque converter was too big and broke the pump gear so I took the old and put in on the new one with a new torque converter and it works now. The old trans had over 300k and was just burned out. The hole problem was my transfer case it went out.

 

did you try shifting it to 1st and see what happens?

 

this. nvm i see the problem has been resolved. in the other thread this dude started about transmissions.

 

I merged the 2 threads......
