transmission question

i have just aquired a transmission and transfer case from a friend for free. i belive the trans is a t-5. he had it behind a chevy 350. would this be a good swap for my 304? and he had this in a unknown year cj-5. another quick question. does the t-15 start off with 13-07?

 

Re: transmission qustion

There are some pictures of Jeep transmissions at http://www.jeeptech.com/wiki/index.php/Transmission/Factory that may help.

Any original Jeep aluminum case transmission, except for maybe the T176, is going to self-destruct behind a 304. IMO your best bet if you want to replace the T14 is a T15; second best is a T150... Nick doesn't like them much, but they seem to hold up pretty well and they are cheap, compatible and available.

 

Was it here that I read that a world-class T5 won't withstand the impact load generated by a Jeep? Maybe they will - it could be an expensive experiment.

 

Let me go against the flow. Way back when I didn't know better I bolted a 307 in place of my 2.5 to my T5 it lived as long as I had it for 2 years and did after I sold it. The T5 is rated for around 225 to 235 ft lbs of torque. I drove as my dd and really wasn't that hard on it even if I stuck in mud. So it will live behind an eight, Mustangs and Camaros used them until the World Class came out. World class uses upgraded bearings and synchros and a higher first gear. In reality the are better options out there if you want to be able to abuse it. I say if you got it and want to use it, go for it but you gotta know its and your limitations.

 

lynn where the trans goes to the transfer case is round not texas shaped.
im gonna try to post some picture i just took of the trans.

 

do you think this set up will fit into my 5? im still not sure if i should try to get this to work or jsut to sell the t-4 and the t-14 and get something i know will be ok.

 

The T-4 isn't worth much, but you should be able to sell the Dana 300 easily. The D300 has a better low-range than the Dana 20, but the transmission choices aren't great.

What are you looking for? Cheapness? Strength? Gearing? I'd say your T14 is a much better choice than the T4. You need the T4 bellhousing too.

 

i have the bellhousing its just not in the pics. the other day i was driving home from work and the second gear in the t14 started to make a really hard knocking sound. so now im just trying to find a good solid trans to put in that i wont need to worry about. right now im not going to be doing that much offroading. the only place i have to do it is a hundred and fifty miles away from me. it isnt anything to crazy just mainly logging roads on my indian reservation near shawano wi. i would like to have a t-18 but i really dont have the money to shell out for one of those. i was just wondering what are t he limits to a t-14?

 

Well, it's a Borg-Warner 3-speed transmission with a cast iron case. Jeep only used it behind 6-cylinder engines; the V-8s only got the T-85 (very early), the T-15 or the T-150. The T-14 is not as strong as the sturdy T-15.

I'd say take the T-14 apart and see what you have. If there's something seriously wrong with the T-14, you may as well look for a T-15 or a T-150 to replace it.

 

when i bought my jeep last summer the po said he just got the trans rebuilt and only put a hundred miles on it then parked it. how much do you think i would be able to get if i were to rebuild the t14?

 

Another option IIRC would be a T176 if you can get your hands on one I think but won't swear to it that it has the same bolt pattern as or close to it as the T4-T5 or may have to redrill the bellhousing at any rate it will bollt up to your 300.

i just found a t15 on ebay i think i might try to get that one. i really didnt want to go back to a three speed but its not that bit of a deal.

Sorry you don't like the 3-speeds. They don't have the crawler gear, but I find them ok driving around. Sometimes I wish I had a gear between 2nd and 3rd with the truck, but I didn't have that problem with a V8 CJ.

The T-176 (as jd7 suggested) is a possibility - it's not as strong as the T-15, but it is a close-ratio 4-speed, and you should be able to redrill the T-4 bell to fit it. They're a medium-duty transmission, and are more breakable than the T-15. You could use the Dana 300 with the T-176, and get better low range gearing.

Just an idea - you might want to look for a rusty CJ with a T-15 locally; that would save shipping and provide any extra pieces you might need. You'll also do better on any local 4-wheeler forums or bulletin boards than you will on ebay.

 

i didnt say this at first but the t5 came off of a chevy 350. the chevy and amc bolt patterns are different right?

 

They never should been put in Mustangs and Camaros. I busted 2nd gear in a couple of them in Mustangs. POS's that I would not put in a Jeep. My $.02

 

Well it depends. There is a bellhousing that came on the 151(2.5) that has the Chevy pattern on the engine side and the T5 on the trans side. I assumed that is the setup you were using. Can't see someone going to the to the trouble of putting internals in a GM pattern case for a trans that will work but like everyone has said is at best marginal.
I think this is one:
