I'm new to the E40D, but I've heard that I'm lucky to have gotten 150k out of mine. (until now). I lost my parking gear. The truck wouldn't start after I drove 15 miles and stopped. I had to move it to Neutral to start it, and it seemed to shift o.k. I have no parking gear now. If I move the selector all the way to the left, I get reverse. I was low on fluid (3 quarts) due to a tailshaft seal giving up the ghost without me knowing. What am I looking at for a repair? Total rebuild? Is there something I may be missing with the linkage? Please use small words, I'm kinda retarded.

Thank you in advance!

 

So, you say you had to put it into neutral to start it, when you are in neutral, what gear is indicated on the dash?

 

When I'm in neutral the indicator reads right in the middle of Reverse

 

I'd check the MLPS on the side of the trans and see if it needs adjusting mine will do that every now and then show the wrong gear on the dash than what im actually in.

 

OK, I'll see if I can't find out what an MLPS is in my Chiltons, and check on it in the morning.

 

MLPS = Manual Lever Position Sensor, it's the electronic thing on the driver-side of the trans that has like 6 wires coming out of it, and it's used to tell the transmission computer which gear you've selected up in the cab with the shifter. I do believe that your issue could be elsewhere tho - parking gear is not something controlled by the MLPS, it's purely mechanical setup so unless something in the transmission shift linkage got bent or broke or slipped out of adjustment you should have park with the shifter all the way up regardless of what the indicator on the dash says or if the truck starts. Reverse gear is the same way, one position down from park, regardless of indicator reading or MLPS adjustent. So try this - with the engine off pull the shifter all the way up (ignore the gear indicator on the dash, go by feel of hand) and then try to move the truck by pushing it (get a buddy or two to help with that, these trucks are generally too heavy for one person to try to move), if she stays put then your shift linkage is good and your MLPS probably just slipped a position, but if she rolls then you have physical damage to the shift linkage that causes the shifter to be a position off from the transmission (or the transmission to be a position off from the shifter, it's the same thing). Report back with your findings on this, and we'll proceed from there...

 

I jacked up the rear and looked at the tires while in different gears. All the way up (the left) puts the truck in reverse. Next to the right comes Neutral and then drive and so on and so on.

If it helps, this is a 92 F-350 crew cab long bed 4X4 with 35's. The tranny shifts smoothly through the gears and everything else seems to work as it should. I have no issues starting it (in Neutral) and going about my business. But, I like to have things work as they should so what is my next step. I guess I should have my wife get in and shift through the gears while I see what's going on with the shift linkage, but I may just wait for a buddy during the weekend. My wife in charge of one ton truck movement with me underneath has "BAD IDEA" written all over it.

Did I accomplish the same thing as pushing it while in the first gear? I think I have, so what is the fix for the MLPS. Oh, and thank you for the explanation and help.

 

Maybe your cab is sagging and the adjustment changed?

 

I really think you have linkage issues, and not MLPS issues - if the linkage was spot-on but the MLPS slipped it would tell the PCM the trans is in neutral when it's actually in reverse, which would freak the PCM out - the fact that you shift through all gears just fie tells me the transmission lever position and the MLPS settings match, and it's just that the linkage between the transmission lever and the shifter got messed up somewhere... Still tho, do try to push the truck with the shifter all the way up, this will be the dead giveaway if the linkage is indeed the culprit.

 

You have loose T30 screws at the bottom of the column.
Tighten the two screws and if should be fixed.
