When my transmission goes into overdrive, transmission slips like it is in neutral. 1st, 2nd, and 3rd are o.K. If I shut off overdrive truck runs fine. Is this a transmission problem or is it something with a switch or computer issue?
Do you

Hey FORDQUESTION0785,

It sounds like you could have a pressure control solenoid that may be out. Here are instructions and diagrams below to show you how to replace it, if this does not work then there is a chance the transmission is going out and needs a rebuild or replacement. I would recommend a service but it is too late for that, the overdrive clutches are burned up.

If so here is a video on how to remove the transmission on a similar vehicle so you can get a rebuilt unit.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Hello,

They do not have a band in newer transmission there are just clutch discs applied by pressure servos. If your transmission is slipping it probably needs a rebuild which is not as hard as people think. Here are the diagrams to do a transmission rebuild on an automatic.

You will need to remove the transmission first this guide will give you an idea on how to pull the transmission out.

Yours will have converter bolts and cooler lines but its about the same.

Check out the diagrams (BELOW)

Please let us know what happens.

Cheers, Ken

My ford pickup kind of slipps in reverse or at least the eng. Reves up but doesn't back very good. On a small incline it takes a lot of throttle to get my truck to back up. It even shutters a little. I'm broke and have 0 dollars for repairs. Please help.

Have you had the fluid flushed yet? Check the tranny fluid pressure. Have it scanned for transmission codes.

Shakes or Wobbles problem
2004 Ford F150 V8 Four Wheel Drive Automatic

My ford truck set for a while due to gas. When I started to drive it again on a take off it chaters till it hits about second gear. Does it more on turning than going strait. Only from a dead start. Rolling start ok. Is this the trans. Slipping or is this in the rearend?

A trans usually won't go bad from just sitting. I would suggest, since it's worse when you turn, to check the CV joints and the u-joints.

Let me know what you find. Also, make sure the ATF is full.

Hi there,

Thank you for the donation,

These additives are not a cure all, at best they may just mask a problem, the slippage is a sign of worn clutch packs leaking servos or low line pressure, it really needs to be checked out now before you do some real damage driving it about, get it seen to by a qualified trans tech before its to l ate.

It may not be downshifting correctly and slipping.

Have it checked at a trans shop to confirm the failure.

Have you serviced it regularly?

Try gear 1 to move forward if in drive it may be a roller clutch let go otherwise have a trans guy check it. Also check fluid if dark brown or black go to a trans shop
