I have a 1997 f150 4wd its automatic with button 4wd. I was recently driving it and all of a sudden it dont want to shift into drive but if you bring up the rpms for about a min it'll slowly get going. I've changed the transmission filter still doing the same. My buddy said i need to get a full service on my transmission. I dont know what to do I need some advice on what to do. I am now without a vehicle so the sooner the advice would be greatly appreciated thanks a bunch

 

filter ? i would be checking the oil condition and level. If level is full , you probably have bigger problems. If oil is burn, or lots of crud in it, you probably have bigger problems. How many miles ?

 

ya the filter inside the transmission the tranny filter and it has about 150,000miles on the truck

 

What did trans pan look like inside? Any crud or shavings?

 

no shavings just some greyish pasty stuff stuck to the magnet

 

Is it a 4r70 or a e40d?
If you have a 4.6 it's the 4r70 and the 5.4 came with the bigger e40d in 97,98.
Sounds bad, you may be just wasting money on a filter or flush! ):

 

how do i know for sure what kind of transmission i have is there anyway to look on the transmission to find out

 

What motor do you have?

 

i have a 4.6 in the truck

 

Then you have a 4R70 transmission.

 

Im not an expert but if the fluid was not burnt and a new filter did not fix it, you have serious issues. I have rebuilt older ones, not sure if the newer ones have pumps etc. but it sounds to me like you need a new or rebuild. Sorry to say!
