    Hello ,

    i was ordering parts at 4wd , the technical guy told me that the t14a will be to weak for my engine (305 chevy tbi).
    i was afraid, so i've phoned advance adapter , and they sais they some customer riding the t14 with v8 without problem.

    Is there anybody who has any experience of this tranny ...
    i have two of them ,so i would like to search for an other one ,
    especially that for an european guy finding a segond hand tranny of an american car ...... i will have to buy it on ebay ... :twisted:

    thank's :beer:

    Your success will mostly depend on your driving style. Be nice, and it'll last. Abuse it, and you will break it. Shift slowly, no burn-outs, and only use as much throttle as you need.

    The T14A is a fairly strong transmission, although not the strongest that Jeep used. Originally it was paired with 6-cylinder engines in the 150HP range. Both the T15 and T150 are stronger 3-speed transmissions, but neither will work in place of the T14 without some modification.

    thank's ,

    it's strange , when you look into advance adpter catalog,
    they describe the t14 as the t150 as medium duty;
    when you open them there are pretty similar in pinion and tooth size .
    Why the t150 will be stronger than the t14 ?

    anyway i already feel a bit more confident , and will use the t14
    as i don't have any thing else ....

    With your wheel base, why not use a Turbo 350?

    How much would it cost to have one rebuilt there?

    Here it's common or was last I checked TH350 $350 USD, TH400 $400 USD.

    I just took one in dropped it off and took a rebuilt one out of the tranny shop that they had on the shelf. But then they're probably more common here than in Europe.

    a few month ago , i was searching a th350 , i've found one 1000$,
    he sais it was rebuilted... but i'm sure not the perfect way ,
    plus the adapters , it will cost too much for me ,
    i ride already the cherokee in auto , so even i know auto is great
    for off-road ,
    i think i will go for a stick into the cj6 , more fun , and easier to do the as.... . i think it's the way you say it . R)

    The T150 was used in V8 CJ-5s and CJ-7s with good reliability from 1976 to 1979. I have not owned one of these vehicles, but I do know that the T150 had a good service record when new. I also believe Novak when they say that the T150 will stand up to most V8s http://www.novak-adapt.com/knowledge/t150.htm

    I can't cite a specific source, but it's my understanding that the T150 behind the 304 V8 had a better service record than the T14 behind either the 225 V6 or the 258 I6.

    BTW the T150 was made by Tremac, not Borg-Warner as listed on the Novak web site.

    Re why, I don't know exactly. I'd guess it's simply a newer design than the T14 and has better alloys, technology, etc.

    hth :)
