What trans is in my truck?

[RustyJeep]

I have and '82 J-10 with 258 and 4-speed manual. I belive that would make it a T-18 wouldn't it? If and whatever it is, will it bolt up to my 360 if/when I drop it in there? Just kickin around the idea a little. Don't know whether to stay with 258(current has 160k on it and looses a little oil pressure when warm) and "warm" it up a little or to drop in a 360(possibly "warmed").

Thanks

Not sure if the tranny is T-18 or not but if it is bolted to a 258 now, it should bolt right up to a 360. I had a CJ-7 in my junior jeep days and replaced the 258 with a 360 and everything bolted right up, even able to use the same motor mounts believe it or not!! http://www.ifsja.org/ubb/biggrin.gif Anyway, check the tech section and you should be able to find info on whether you have a T-18 or not.

ok, after looking in the tech section, I found that I either have a T-176 or a T-18. How could I tell the difference in my truck? What do I look for?

The best way to tell between a T-18a and a T-176 (got to give credit to Scotty for this) is that the T-18A has a granny gear. It is really low and does not have a synchro on it. If you can step on the clutch and put it in first without grinding gears (giving sychro time do do its job of course... 1-2 sec) then it is the T-176. I just rebuilt mine and could not get parts for it anywhere in Canada.

I had thought about changing mine to a 360 too ('74 has 360 now), but with the milage difference and what I was using it for, didn't think it was a good idea. Plus, it wouldn't have been stock now would it http://www.ifsja.org/ubb/wink.gif

If it's stock it's a T-176. In 1982 the T-18A was optional only in the J-20's.

the t176 is a medium duty trans.how long it will live behind a 360 will depend for the most part on your right foot.

to drop in a 360 you will need v8 frame and motor mounts. the next prollem that you will have is that the 360 and 258 are different lengths. the 360 sits a good 8 inches further forward in the engine compt. a manual trans behind a v8 will have to have a spacer between the belhousing and tranny and a longer input shaft. otherwise,when you drop your new 360/t176 into the truck youll find your shifters have moved forward,due to the further forward placement of the 360. this will put the tranny shifter right about under the dash-i doubt youll be able to shift it.

you will also need some new clutch linkage pieces. the bracket for the bellcrank moves forward on the frame with the engine,so youll need(at the very least) the rod that goes from the bellcrank to the pedal assembly as your 6 cyl one will be too short.

the core support is also different. youll need to either swap the radiator core support and swap in a v8 radiator,or be stuck with a custom 3 row core of 6 cyl size. the 6 cyl radiator position may have interferance prollems with a stock clutch fan,so you may need an aftermarket fan and spacer,or an electric fan.

dont forget the little things like a v8 throttle cable,some minor rewiring to reach all the accessories and the distributor,and make a new exhaust.

last and not least,you will need a 360 flywheel.the 258 and 360 are balanced differently,so youll have the shakes if you try and use your stock 258 flywheel.

dont mean to discourage you. the easiest way to do it would be to trade your truck for one that came with a 360/t18. if your truck is nice,and you can come across a dodor cheap,and dont mind the work,the next best option is to find a donor truck with a 360 and swap in the engine and whatever trans is in there into your turck.id highly reccomend trying to find one with a t18. if you have a whole parts truck youll have all the little stuff youll need to do the swap correctly,including driveshafts,and you may be able to make some back selling off what is left.

good luck with you project.

Reading your posts is like looking at a great painting (if you like art that is). It is always a pleasure knowing someone has obviosly grasped the full concept of "GEARHEAD". Your input is most gratefully appreciated from me http://www.ifsja.org/ubb/smile.gif

In regards to replacing the Automatic with the manual tranny--

It can be done, apparently. My FSJ has a chevy 350 and a manual(350 or 360 I'm guessing), tranny. The shifter is pretty much under the dash, but rather easy to shift due to the custom shifter that has 2 bends in it.

My tranny also has a non-syncroed 1st granny gear that's pretty much useless, so I do all of my shifting from 2nd-4th.

thank you jod man http://www.ifsja.org/ubb/smile.gif i do what i can to try an help people.

as for the chevy/manual tranny,this is somewhat apples and oranges.im not real familiar with the chevy trannies,but the 2 granny 4 speeds that cometo mind are the sm420 and the sm465.either which way,there are lots of factors to consider,and when doing a custom engine/tranny istallation it is quite possible to postion drivetrain further back than a stock 360/t18 would be.

sure,it is posible to replace a 258 with a 360 or a small block chevy,and keep the same tranny.some creative bending of the shifter may do it,but now you need to also move the crossmember forward,and make new driveshafts.and its crossedover the line from a "quick bolt in" swap to an "engineered project".

it all depends on how much custom work your willing to do.i personally do not feel the t176 is worth retaining behind a 360,especially if youll be doing any towing or 4 wheeling.the t18 will be a much more durable tranny,and youll really appreciate the granny 1st for getting a load rolling,or crawling up a really steep hill.

sam,waht year is your jeep? are you sure youre using a chevy tranny?are you also using a chevy xfer case? what diffs are you running?

a chevy 350,sm420,and 205 xfer has the makings of a real nice trail crawler...

Scott, I just took delivery of the Jeep, so I haven't even had time to I.D. the tranny or Xfer case on it yet. It's a 1966 Waggy with a Chevy 350 in it, so I'm assuming he took the Suburban tranny and transplanted it as well.

Xfer case might be Jeep, but might also be Chevy, no clue yet.

[RustyJeep]

Well, that pretty much sums it up. I was kind of leaning towards just building my 258, and you guys have shown me the light. I really like these engines anyway. So bulletproof (in my mind). Maybe I'll do a 4.0 head conversion to mine while it's out. Now ya got me thinking.

if you can find the whole 4.0 engine,you can build a stroker using the 258 crank and rods. it gives you 272 cid,and around a 9.5 to 1 compression.this is what im gonna do with mine,as soon as i find the engine.you can find out more about it here if the idea interests you : http://bc4x4.com/tech/bryce/stroker/stroker.asp
i agree with you completely,the six is a durable,hard working,give you no crap engine. im sure id be on at least my 2nd,or 3rd small block or 360 if thats waht i was using. ive overheated mine real bad,more than once, one time to the point of blowing the top tank of the radiator in half.not to mention running off camber,almost on its side,or going down steeeep hills with no oil around the pickup,light glowing brightly. and it still keeps chugging along...

Ok Scotty, this weekend I have to replace the alternator(****ed thing broke down on it's inaugural drive home when the battery died), and battery, so I'll make an effort to ID the axles, tranny, xfer case on it.

it should prove to be an odd combo, no doubt. http://www.ifsja.org/ubb/smile.gif
