No more drive!

[nolongerjips]

Ok.. my tranny has been living on borrowed time for a while now. I posted a thread called "Reverse getting worse" a month or so ago, where I explained that reverse slips pretty bad - but still works.

Heres the latest frustration!

2000 Explorer XLS 4.0 OHV 4x4 with 5 spd Auto

I drove about 20 miles from home yesterday to pick something up. Lo and behold - I try to drive away and the tranny will not engage forward whatsoever. Reverse works! I drove in reverse about a mile and half to a church where someone could find me. I finally figured out that if I put the truck into 2 or 1 - it will drive forward - and then I have to shift into D/OD after the truck builds up speed. all gears shift ok and they all work - but it just wont move if you try to start off in D/OD

any ideas? might this be just valve body stuff?

I had this condition once on a 1966 OLS and it was a simple O RING THAT goes between the pickup and the filter... I think this is a good place to start assuming you already checked the tranny fluid level.. George

 

[nolongerjips]

yeah I checked the fluid. The filter was replaced and it was flushed maybe a year ago.

So this is something I can check by dropping the pan and looking without ripping out the tranny

Check the valve body gaskets for signs of deterioration, and the torque of the valve body bolts while the pan is off.

 

[George W]

Yep just pull off the filter and have a look see.. George

I got a 92 ranger..Only reverse,no forward..I checked the filter O rings they are new..
But could somebody tell me where/what is the valve body?

 

[BrooklynBay]

The valve body is the brain that routes fluid to each section of the transmission. The passages look like lines on a map. Check the sticky thread in the transmission section called the A4LD valve body rebuild diary for more information.

i have this same exact issue on my 97 with the ohv engine. did you happen to find a solution to your problem? any advice would be great!

 

[Blueraven]

I've got the same problem, however after a week or so, the "going to 1 or 2, then back to drive" quit working and now all I have is reverse. The truck is a 3rd vehicle, so I haven't been in a rush to get it fixed. I was thinking of taking it in this week. But perhaps I should pull the pan and take a look see. If you find something, let everyone know.

Thanks, Blueraven

One more thing, does anyone have any indicators other than "no drive"? I have no OD light or codes. Also, if I lift the rear end up my back tires do slowing rotate.

You still have some engagement if your tires are moving. The pressure is probably too low to make a firm engagement into gear. Check the main pressure, and the EPC pressure ports with a 0-300 PSI gauge.

sorry "nolonger", I didn't mean to hijack your post.

i have no indicators other than the malfunctioning issue. i have to put the truck in lw 2 tho, then into d once i get going. it acts the same in low 1. i can feel it want to engage and go, but it just wont. Brooklyn, what and where is this valve body you mention? i would like to take a look at mine, but unfortunately (or fortunately lol ) i havent encountered transmission issues before and not too familiar with their components. you also mention EPC, what is this? one last question. i have the 4.0 ohv with the control trac 4x4. what transmission model do i have.

 

[BrooklynBay]

The 5R55E valve body rebuild diary has all of the information on the valve body: http://www.explorerforum.com/forums/showthread.php?t=140987

 

[kingpin0810]

where is the valve body located? do i need to drop the whole tranny, or is it accessible by removing the pan?

 

[BrooklynBay]

Drop the pan, and you will see the valve body. It could be removed while the transmission is still connected to the vehicle.
