help! tranny questions

hey guys I have a question or two about mounting my new transmission. When I purchased my jeep cj8 the t14 in it was done for. the guy included a t18 with a dana20 tcase in the bed of the jeep. i was going to drop the t14 today but when i checked it out it looked wrong. not sure if its missing the bell housing or what. the motor is a re manufactured 258 by titan motors in ocala florida so maybe its not a jeep 258? not sure. also Im not sure if the t18 is a ford or jeep but ill include pictures for you guys to look at. i have taken out a manual tranny and put it back in before i just have questions since im changing to the t18. i know i will most likely have to get different length drive shafts but what else am i going to need to swap them? any help would be greatly appreciated! thanks

this ^ is the t14 that is currently in it. i dont think the insides should be showing like that. guy said he wheeled it all the time until it started missing gears.

this ^ is the t18 sitting in the bed. not sure if output shaft is right and hopefully the mounting holes are correct.

theres the whole t18 and dana 20

looks like a 258 but it could be a 232?.That looks like s Jeep T18 a FORD T18
would be 2wd and not bolt up to a transfercase. check the numbers on the cases. It could also be a T19/20 out of a Scout. There is a grannylow first gera T18 and a 4:00 first gear T18. One T18 has R up and one has R down.

Im sure its a 258 just not sure if it was originally made for a jeep because of the weird way the t14 mounts to the motor unless thats normal for a jeep. and its the t18 with granny low. my biggest concern is whats up with the inside of the t14 showing and is the t18 going to mount up to the motor correctly and if the output shaft is the right length.

Its missing the seperator plate between the engine and trans. Im not sure what this would cause on a manual trans but it could possibly put the input shaft slighlty too deep into the pilot on the crank. Its a little more important to have for setup on autos with torque convertors and for starter motors that mount to the bell housings. I would find a seperator plate to put back on there.

Im not too familiar with the T18's as far as ford, jeep, IH etc. I can tell you that your T18 is missing the nose cone, that cone covers part of the input shaft up to the splines and also the input bearing. I suggest you to google the T18 swap to find some info on the internet, its not a bad swap but you will need to do a small amount of fabbing and/or need a couple more parts.

look at the website for advance adapters this may help you.

When I did my T18 I had cut out the bottom of the skid plate flip it and reweld it.

You need to measure the input shaft. Fords will be 6.5" from the face of the transmission to the pilot tip, Jeep CJ will close to 7.5" How is the t18 mounted to the bellhousing? All 4 bolt heads on the trans side or do the 2 bottom come out from the bellhousing side? You need the front bearing retainer or it will leak and the through out bearing rides on it. You are missing the engine plate between the bellhousing and your motor. Just make sure you have the right pilot bushing and you should be good. It does look like a CJ T18 to me from the long pilot bushing surface.

thanks for the input guys. all four of the bolt heads are on the transmission side. ill measure again tomorrow in the day light but when i just measured it seemed like the input shaft was about 7 inches? my question is where should i get the seperator plate from? (as well as the other parts you mentioned) i dont know if i should find a jeep junkyard or go to a local tranny shop or autoparts store? and how big of a dent are they going to put in my wallet? im kind of stuck because I basically bought the jeep over the phone and i was unaware of the work to switch the tranny's since he made it sound like it was easy and that all i needed was a different pilot bushing (not a 100 percent sure what that is) and different length drive shafts.

Take a pic of the front of the T18 I may have misread your pics thinking the one missing the bearing retainer may have not been the T18,

you mean other then the one in my original post? the picture of the tranny connected to the motor is the t14 that doesnt work and the picture of the tranny just laying in the bed is the t18.

there are two pictures of the t18

You need the bearing retainer for sure. Any trans shop that does gear boxs should have one.
