i have a 3 speed fmx in my 67fastback and i want some kind of 4 or five speed. toploaders seem to be the tranny of choice but i dont know why. what is the difference??? also, is there any specific truck i could get an old tranny out of that would bolt up to my 351C? i dont want a truck tranny that first gear is a crawler, unless its a five speed where i can start in second when i want to... i also want something that has an overdrive in it, perhaps a four speed with overdrive or three speed with overdrive. any information on where to get a tranny for my car would be appreciated. i live in washington, so if there are any people that know of a closeby place to get one, please let me know. thanks

The Cleveland shares the same bell housing pattern with the 302 and 351W.

 

..and the 300/240 big six, 250 little 6, 3.8 rwd 4.5 svo
how many did i miss?

as far as a manual the ZF 5 speed is the only way to go even tho a junk yard toploader would be cheaper the ZF will give you a low(there are different gearings) AND A OVERDRIVE omg
to the junkyard you go


heya eric what pattern does the modulars use?

 

still im pretty stupid... i dont know what a ZF 5 speed is. any idea what gear ratios they would be? mostly applying that question to first and overdrive gears. also i thought it would be good to tell you guys that my 351C has close to 425 horse... so i also wonder if these trannies we're talking about can handle this. i would think so but its better to be reassured...thanks

 

Moved to the trannsmission forum for answers to those questions.

 

See page 36 " Tremec 3550"
And page 37 "I don't understand the C4"
And page 39 "Where can I get a C4 manual...."

If you want info, this should cover it. If you don't want info, but just like to get posts to your questions, well, you're doing good there, too.

 

ZF 5 spd is truck transmission. That's one H-U-G-E trans. You don't want that trans in 67 Mustang otherwise you'll have to hack up the floor badly to make it fit.

 

thanks for the advice on that one! if the ZF is an obvious no for my fastback, do you have any suggestions of what one to get since it seems you know what will fit in my car? i need to learn a little more...

 

Toploader 4speed, AOD auto overdrive, C6 auto no overdrive.

 

C4 will fit as well. But it would need to be beefed up a bit which I heard can be done. These are preferred in most cases because they do not suck as much horsepower as a C6 does. I have a 302 with a C6 in my 83 Ranger and that transmission is slowing it down big time. I thought I saw the guys on horsepower TV do a 5 speed swap on a 66 or so Mustang quite a while ago. I think they used a TKO T5 but am not for sure.

 

I'd go with a built AOD. 4-speed transmission, good overdrive gear, and it can take the abuse you will be throwing at it, and its not hard to build up either.

For manual...either the Toploader 4-speed or, if it will take a 425 horsepower Cleveland, a T5.

Yeah...ZF would be WAY too big.

 

the only reason i didnt want to go with the t5 was because i heard it didnt bolt up right. i dont want to make this whole project a pain because of my limited knowledge (cough cough) but i also wonder if the toploader can withstand the stuff i want to throw at it??? and whats the AOD, and where could i get one...as in what type of vehicle was it in or something like that? thanks for the info...

 

The AOD is an automatic, and from what I understand you want a manual. I would think that the toploader 4 speed would be able to take much more abuse that a T5. I don't see any issues as far as the T5 bolting up to the Cleveland. It has the same pattern as a 302 so it should work. You might be able to get a T5 TKO to handle the power of that cleveland. I guess what it all comes down to is how much you are willing to spend.

 

i do want a manual. from what i understand the tko is pretty spendy. id rather have a toploader 4 speed. i am dutch...very very dutch, but practical. where would i be able to get a toploader 4 speed? what specific vehicles had them? and would i be able to find one at a junkyard? would it have to be rebuilt? how much will it cost? thanks for the info...again

 

The toploader 4 speed was pretty much found in cars through out the 60's and 70's. I do not know the specific years but your 67 was probably available with one when it was new. I do know they were found in more high performance cars like Boss 302's, Mach 1's, Cougar Eliminator's, and so on. Toploaders may be a little hard to come by in a junk yard but you could always get lucky on that. I have seen a few on ebay from time to time though. As far as rebuilding one. It may be best to inspect the inside and see how it looks. At minimum, a new set of bearings and some new seals should suffice.
