About 2 months ago I bought my 93 f150 4x4 with the 5.8 and the e4od tranny. I've put 3,000 miles on it so far and the only problem I've had was a hard shift from 1st to 2nd. But now I will be accelerating and it will violently shift.. Also when I'm taking off my engine will rev up but just coast for a few seconds then it will start going. I checked the tranny fluid and it seems to be a god 2 quarts over. I'm changing the fluid and filter tomorrow but what do you think can be the issue?

 

the fluid being low/high will cause that. make sure to check the fluid when running and warmed up also. when i first got my 150 going again i was 2 quarts low and it wouldnt even shift into gear, if im more then maybe a quarter of a quart low/high it will shift weird.

 

This is a FYI post..If you have any of the following codes.."637" Trans oil temp signal high...626.. Coast Clutch solenoid.....624 Electric Pressure control circuit.....Check you wiring harness,you may have burnt out a few wires..these wires are right next to the heat shield by the cat. Over time these wires will get burnt out. But dont worry you can buy a new harness on ebay for about 35 bucks,you then splice the new one in, and waalaa..tranny troubles gone! Hope this helps
