I have a 99 f150 5.4 and I'm wondering if my problem is a transmission problem or something else. When I put my truck in reverse it is fine. But once I put it into drive I have to rev my truck up for it to more or less "catch" and start driving. The problem has recently got worse where it slips out of gear while driving and at stop signs then I have to rev it up again and it will finally catch and go into gear and drive. If I rev it up too much it will jerk the whole truck making the tires squeal. I wanna kno if anyone knows anything about this problem. I recently turned off my over drive and now the problem only happens when I shift out of park or reverse. But like I said reverse still works fine.

 

if it were my truck, i'd say it was transmission....i would highly doubt torque convertor (thinking out loud) ..how many miles you have on it?

 

Try down shifting to 2nd then 1st when stopping. But thats just to help mediate the problem.

Hows the trans fluid level?

 

145,000 roughly

 

Fluid is good and pink...

 

if it slips out of gear when you drive, then the tranny is shot.

 

I had the same problem with my truck and it turned out that the tranny was completely shot... Hellllllloooooo huge bill.

 

****ty deal man it sounds like the trans is toast but if u can find a good used one for chap it won't be to steep of a bill
