I have put a ford refurbished tranny in and rebuilt the shifter assembly twice - 2004 mountaineer. Why am I still getting hesitation going into gear? intermittant problem, most going from park to reverse.

pull boot up you will see 4 bolts put tranny in neutral take bolts out pull shifter straight up don't move anything until you replace shifter

Your differential is upside down. Ford model T's had the same problem. It was possible to mount the rear axle upside down which made the car go forward in reverse and backward in forward gears.

no other symptoms.?
is it the engine that hesitates or the slushpump A/T tranny.

RPM of engine tells you that.
goes way high? that is slip, bad tranny
stay about 2000RPM max with brakes held.?
fail; hot or cold engines.
or is this post, that when you move hand from N to D there is a delay
you never said what is delaying , car movement or shifter to trans engagement.? or ?

Strip the tranny again and check that you have not blocked the oil ways. and that all the pistons and valves are working freely

I HAVE A 1989 F150 4X4 WITH 5.0 LITER AND A 5 SPEED TRANNY AND ALL THE SUDDEN THE SHIFTER STARTS FEELING LIKE ITS NOT WANTING TO GO INTO GEARS PROPERLY AND ITS HITTING THE DASH NOW WHEN I TRY TO PUT IT IN FIRST GEAR AND 5TH GEAR IS KINDA SWIRLY FEELING ALSO WHATS WRONG WITH THIS TRUCK ANYONE KNOW WHERE TO BEGIN WITH THE REPAIR OF THIS TRANNY

On the top of the gear box remove the bolts that hold down the shifter plate.Pull up on the shifter and it come off,stuff a rag inside the hole to keep debri out.

if this is a standard tranny the problem is more than likely in the top cover of the tranny one of two things either the nylon seats for the shifter ball are worn out, or the shift forks are worn down and have slipped out of the sleeve they sit in inside the tranny. can usually get a rebuilt top at a resonable cost pretty easy to change out. can be done through the floor board by removing the shifter and console.

its the ecu on the passenger side i went thru 3 trannys in 4 months and they finally looked for the problem because the tranny was under warenty and they had to keep fixing it for free

Just to let you know that I just got my care back from the tranny shop. I had not had a problem at all and just the other night after picking up my son , got in my car and it hesitated to go in reverse but it and it bucked real hard twice. Did a little of the same ..but anyway...the tranny place has to replace the lock nut on the main shaft. Remove side cover of transmission, replace self loking nut on main shaft ..nut came lose ...$320.00 So I was very happy I didn't have to have a valve job, sylenoids replaced or rebuilt tranny.
