AMC 401 conversion help
Happy New year to you all, and thanks for all the posts so far. its been awhile since i've been on. Right now I have a T-4 in the jeep, and a T-18 sitting in the garage waiting to be installed. i'm starting to have slight doubts about putting the T-18 in, mainly due to the low first gear. there isn't going to be any serious wheeling done with this jeep, nothing that i could see needing a crawler gear. the T-176 from what i've been reading seems to be a better fit, but they are turning out to be quite hard to come by. chances are i will be going with the T-18 since i have it sitting in my garage. any thoughts from you all with the t18s in respect to minor offroading and street use? thanks again for all the replies
Very interesting thoughts, I thank you very much for the input. I'm new to the jeep world, and all the possibilities they have to offer. I've been driving a 5 speed dodge dakota so that's pretty much all I know as of right now. Its taking me a little bit to wrap my head around the idea of anything different than driving a 5speed. The T-18 came with a Dana 20 Transfer Case , at least that's what I was told. Sadly I have not had a chance to verify that. What are your thoughts on the Dana 300 vs Dana 20 Transfer Case ? again thank you guys for your input.
The advantages of the Dana 300 over 20 are its eaiser to twin stick and has the lower crawl ratio. Since you are not wheeling hard, may not be as importaint, but the Dana 20 requires an adapter i think to mate to that T-18 ...
Not positive but the Dana 300 i think is a direct bolt up.
But you said it came with a Dana 20 attached right?

IMO you have the holy grail of motors for a jeep with the 401. The holy grail in Transmission the T-18 and a stout Dana 20 I would just slap in the T-18 and Dana 20 and run with it. The low first gear of the T-18 will more then make up for th e slight differants in lower gearing of the Dana 300 . But thats just my .02the Dana 20 came bolted up to the T-18 , and the jeep yard told me it was out of a CJ7 . I have a Dana 300 and the Transfer Case in question sitting side by side, and they definitly look to be different transfer cases.
Well the T-18 Transmission with the Dana 20 Transfer Case has been installed! I picked it up last night, and my alternator was squealing really bad, so I didn't have a chance to really drive it. Once I get that replaced then its time to play alittle bit, Ill let you all know what I think of the T-18 then.
Swapping D18 guts into the Dana 20 has always been a popular way to get lower gearing also.Don’t forget that if the Dana 20 isn’t low enough you can swap out the guts with a Teralow kit and get the Transfer Case down to 3.15:1.
