When I shift into reverse and have to back up going up any kind of hill, it has trouble doing it and makes noise while doing it. I guess the noise sounds like a high pitch grinding noise maybe. Anyway, I was wondering what you guys think this might be? BTW, I checked the tranny fluid and it's within the crosshatch. Thanks.

 

Does it do this just during initial engagement of being put in reverse or from the time it engages to the entire time you are backing up? How long since the fluid/filter was actually changed? If it's been awhile might want to change fluid and drop pan and change filter. There are magnets in the pan which you might want to check for debris and should only have clutch material on them, so any metal shavings would be a clue to more serious issues. The tranny has a slew of solenoids and a valve body which could also be contributing if it tranny isn't fully engaging and locking in that gear ( if that's possible). Just thinking out loud on this end. Maybe someone else can chime on a specific thing to check.

 

What year is your truck and what engine does it have? When you checked fluid level, what color was the fluid. If it is blackish, a fluid and filter is definitely needed.

 

I have a 2000 ranger 6 cylinder 182ci flex fuel engine. Fluid level is in the crosshatch and is normal color. A pinkish red color. No traces of metal or anything either. It is due for a change, but the fluid looks fine. I'll change it and see if that improves anything. Thanks.

 

I have there same model truck. Recently my truck developed shifting problems with the 4R44E transmission. When I replaced the valve body the gasket was blown out in the reverse servo area. I would suspect you need new valve bodie gaskets. This repair is within the capability of most people who do their own repairs. I found two UTUBE videos that cover this repair.

Suggestings if you attempt this repair:
1: Keep the valve body as clean as possible.
2. Inspect the oil passages above the valve body for any gasket materials.
3. Inspect the oil passages a second time.
4. Ford sell a bonded gasket/seperator plate for the valve body - Recommended
5. If this is the first repair to the transmission you might consider replacing the valve body. I would recommend Central Valvebodies. They will give you a discount if you mention this forum.
6. Watch the utube vidieos several times. I found little tips and tricks that saved me time during the repair.

In my case the valve body replacement was my first attempt to repair an automatic transmission. Taking my time and checking each step in the process I was able to complete the repair in four hours. If I were to do a second reair time frames would be reduced to two hours.

Hope this information is of some value you.
