Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / February 20061996 F-150 Transmission Slips First 5 Minutes
Hi. I am hoping someone can offer some help on my problem. I have a 1996 Ford F-150 truck with an automatic transmission. For the first 5 minutes after cranking my truck, the transmission slips (I guess that is what it is called). If I pull away from a stop sign, it will rev up some before "catching" and going. The fluid level seems OK. This only happens when it is cold outside 30 - 40 degrees. It did it last winter a few times also. The truck has 185,000 miles on it. Any ideas? Thank you. > Hi.

Firt thing to check in that sort of situation is fluid level. If that's fine, when was the last time the fluid and filter was changed? If its been more than 50,000 miles, do it. That said, sluggishness when cold can be a symptom of aging/shrinking seals inside an automatic. Probably just a plugged filter, but it could be more. > > Hi.

I don't know how long it has been since the fluid anf filter was changed. I think I have put about 10 - 15,000 miles on it since I got it. I have the filter, just haven't got around to trying it yet. I am glad to NOT hear that a filter change wouldn't help it, and that it is shot. > That said, sluggishness when cold can be a symptom of aging/shrinking > seals inside an automatic.

I think it has more to do with the fact that the lip seals on the clutch pistons get hard and stiff when cold and won't seal against their cylinders as well. > > "Steve" <no@spam.thanks> wrote in message > [quoted text clipped - 9 lines] > pistons get hard and stiff when cold and won't seal against their > cylinders as well. Hi. Thanks again for the information. I appreciate it. > Hi. I am hoping someone can offer some help on my problem. I have a 1996 > Ford F-150 truck with an automatic transmission.

Slipping when it is cold often means that the line pressure is lower than it should be and that can be a result of fluid which is too viscous or has not been changed recently, plugged filter, dirty valve body parts, deteriorated rings or seals, and a worn pump. When I took some transmission classes years ago, the instructor said always suspect the front pump when this sort of behavior was noticed. But, as Steve posted, other things can affect it too. Have you serviced it recently? A service and adjust (if it is one that has adjustable bands) might be money well spent. > > Hi. I am hoping someone can offer some help on my problem.

I am hoping it is just old gunky oil causing the problem, but I wanted to ask some people who know a lot about them. Thank you. |
