problems with t-18 updated

The advice I got when I had problems all worked great. Now I have a new problem. I have everything put together and when I put the shift cover one I can go through all the gears and neutral but after doing it a couple of times then I have no neutral and it will feel locked together. After that happens I cant put it into 3rd, 4th,or reverse. This is killing me and I cant figure it out. Any ideas will be great.Thanks

Re: problems with t-18 updated

An update please. What have you done to the box? And is this while driving on the street, in the shop with the wheels spinning, or just static shifting? And what cures it temporarily, pulling the cover and replacing it?

I might have been born at night, but it wasn't LAST night.

I have it on my bench. I only happens when the shift cover on. I shifted it through all the gears without the shifter on and that seemed to work fine. I think it might be something with the shifter.

Hey Muddy,
Did you lube the shift rods before you put the top back on? You might have some binding on them. Also, put some grease in the socket where the shifter rides. Check the shift rods and the shift forks to see if they're bent. The Hanes CJ service manual has a good write-up about the T-18, check it out.

good luck,
Chris

Another thing. Is the bellhousing on? How about the rear adapter? If not, the bearings have a tendency to work themselves out of the case just enough that they create some extra play for everything in the case and then nothing works right. May be just fine when you get it in the jeep and all hooked up.

Re: problems with t-18 updated

Make sure the synchro's are lubed good also with gear oil. I've seen where they would stick to the cone surface on the gear when static shifting and lock the transmission up. Also check and make sure you have enough clearance between the synchro's and gears.There have been times when I've had to add extra gaskets between the case and front bearing retainer to get the clearances right. Check for bent shift forks, binding in the top, etc. Also, just so you don't have problems in the future, most reverse springs in used T-18's are either worn out or broken. I would recommend pulling the spring out and checking it. I've found that 90% of them are bad. The spring is still available from Ford. If you can't find one contact me, I have a source for them. Good luck. Nickmil.

Re: problems with t-18 updated

Nick, the reverse-gate spring in my T18 is broken, so the shift lever will fall into the reverse gate when going for 3rd. Is that the spring you mentioned? Do you have a Ford part number for it? I know that if I go the the dealer he's going to want year and model. That's they way they are.

Re: problems with t-18 updated

Hi Jim,
Yup, that's the spring. I don't have the part # handy here but tell them it's an '81 F-250 4x4 with T-18. You might try local transmission shops also. They should have them. I would try the dealer first though. Also, be very careful when you pop the Jesus clip off to get the poppet and spring out. They have a tendency to fly away and then you get to say a few choice words. Good luck. Nickmil.
