I have a 1992 f150, 302 with a e4od tranny. About a week ago I noticed the transmission slip as I pulled out of the driveway. It was low on fluid. Now it only slips every now and then. Example: I leave the house around 6:30am, drive about 13 mile, exit the interstate, stop at the light, when I pull away at the light the transmission slips. Truck doesn't move, if I hold the gas and let the rpm get to about 1500 the truck slowly starts to move forward. Once I get to about 10 mph everything works fine. Only time it seems to slip. Runs fine the rest of the time. I don't think there is a ghost messing with me at this intersection. I'm guessing if I drove in a different direction I would do the same thing. No hard swifts, swifts fine. Any ideas?

 

TBH, a hard shift is better than a slipping shift. Are you sure it's an e4od? I thought the 5.0s got aode transmissions when they switched it all over to electronic.

This doesn't sound like a shift problem though, since you're already in 1st gear when this is happening. You also said your were low on fluid... I'm wondering if your actual torque converter is leaking.

 

I called a Ford dealership and gave them my VIN and they said it's the e4od. How can I check the torque converter?

 

What sort of condition is your transmission fluid in?

 

Have you pulled codes?

 

Looks ok, but I just added a couple of qts.

 

I haven't, are these different codes then when the check engine light is on? If so how do I check them?

 

I think they just retrieve like regular codes. I had a code for excessive torque converter slippage that popped up once but went away after I serviced my transmission.

 

Did a transmission shop pull the codes? If not how did you get them? Did you do a full fluid change (torque converter too)?

 

I pulled them through the OBD I connector. I drained the converter and transmission and changed the filter. I didn't do a full flush.
