2006 Explorer No Reverse

[09marty]

Hello,
I have a 2006 Ford Explorer XLT Sport.
I am having a classic problem with my transmission. I put it into reverse and it does not work as it should. I have to apply gas and then I hear a clunk and it starts to reverse. It goes at one speed no matter how much throttle. I would love for this to be a fix that I could do myself. I realize that at 150,000 it would be great to rebuild the engine but I am in college and live in an apartment. So I neither have the space to rebuild it or the money to pay someone. I planned to take the pan off and replace the solenoid pack, filter, reverse servo. I saw that someone makes a servo bore with an o-ring to fix a common issue. I would prefer this over the drill-out method and replacing with a brass sleeve. Does anyone have a link to this product? Do you guys agree that this would fix my problem? I do not believe the reverse band to be broken as it still "kind of" reverses and I can not easily check. Thank you all for your time and input!

I dont believe its the solenoids or the filter unless you just changed it, your only hope of a fix without removing the transmission and rebuilding it would be if its the reverse servo or a valve body issue.

I would make sure the fluid level is correct, then pull the pan. If the pan has debris in it stop right there and reinstall the pan and know that it is broke and will have to come out or the pan is clean and we can check the reverse servo. Remove the 4 bolts that hold it to the case and it will come right out.

You will be able to see the low/reverse band at this point, you could determine if its any good by looking at it but you really need to know what a good one looks like to know for sure.

You can take apart the low/reverse servo assembly and inspect the servo itself, watch out for a big spring under the cover, its not too strong but if you dont know its there it will surprise you for sure.

I have run into reverse issues with the valve bodys on these things but I dont remember what we found probably because we just installed another valve body and if it fixed it we moved on and discarded the bad valve body. I understand you probably wont have valve bodys laying around and just buying one to see what happens could get expensive, so just get familiar with what to expect before you go diving in and see if you see anything that looks incorrect. Checkballs, stuck valves, broken springs, gaskets maybe (not so much with these transmissions).
