I have a 97 7.3 E4OD. Trans was just rebuilt and gone through two times now. New torque converter and solenoid pack as well. When in drive you can only give about half throttle anything more and it will just sit there and slip. Wot and it slips. It’ll slip all the way from first to od. It also slips in manual 1-2. I’m hoping someone here can help me out with this. It’s been two months now and I just want to drive my truck like I used to lol. Any ideas??

 

Do you have LED brake lights or an LED third brake light?

 

No LEDs but one of the cargo bulbs is out. Could that be the issue?

 

What codes are stored in the computer? I predict without the codes you will not be able to fix this.
