3spd and 4spd bellhousing differences
hey guys. I've kinda run into a problem and need some info to figure out my dilema. I got a a 1964 ford f100 with a 292 and 4spd. I am planning on doing a 5spd conversion in the spring. My plan was to use one of john mummerts 5spd adapters plates and then bolt up a tremec TKO500 5spd but now i c john has some new info on his website that says that his adapter is designed for a 3spd bellhousing. I need to know what the differences are between the two. Is the tranny bolt pattern different from a 3spd and a four spd and thats Y theres two different bellhousings??????
Also, I have been considering the notion of converting to a automatic. like an AOD. I am hoping someone on here has done this conversion in a truck and can shed some light on the subject cause i cant seem to find any info on a AOD conversion in a truck. thanks again guys.

Yes, the 3 speed and 4 speed transmissions have a different bolt pattern and yes, there are two different bellhousings.
There is a company in CA which can modify a Y-block bell housing (car and truck) to fit an AOD transmission. Name is Bristol Services Company in Costa Mesa. 949-722-1122 Gary Croan is the guys name. Think the price for the whole thing is about $1,200 (believe that's with you providing the bell housing (to modify) and the AOD and them providing the rest of the parts for bolt in. PM me your e-mail addy and I'll send you a copy of their fact sheet (which I got from another member).

the reason for the tko is that the the correct shifter placement for a truck application and also I have talked to several tremec transmission sources and they are saying for a truck application, the t-5 is to light duty. wont stand up to the abuse and use that a truck would go through plus, it's got a torque rating of 500 or 600 foot lbs and well i drive hard and plan to build my 292 up quite a bit so the tko is the perfect choice from my research.
As far as the bolt pattern, no. from my research and talking to tremec dealers, i am led to believe that the t-5 and tko have the same bolt pattern. wats different is the input shaft length. from my understanding, the pre-93 t-5 have a shorter input shaft than the post 93 t-5. now, if i understand correctly, the post 93 t-5 and tko trans have the same input shaft length.

You might try contacting Quicktime. They make bell housings for the Y block. They might have one which will allow the tko to bolt up with no modifications. If you are going to be able to make use of transmission rated for 500 or 600 footpounds then this bellhousing will be a good investment. ...Oh, maybe not. I just looked at the prices: http://www.summitracing.com/search/D...rd=bellhousing
Are you sure about the bell housings? I'm fairly sure that the Cobra R 5 spd uses a different pattern than the T5. I thought the Cobra R 5spd is a Tko. I thought the lower bolts of the tko were spread farther apart. I looked at all this before doing my conversion but it's been a while.

i could be wrong. and ya i looked at quicktime but the bellhousing they show looks to be for a car application. I have emailed them a couple of times inquiring about a "truck" y-block bellhousing but no response.

Yeah. They are for cars. I guess they think trucks don't like to have fun. I'm sure they can be made to work.
The very 1st Y bell housings they produced didn't even fit. A few of us expressed interest in a truck specific unit since they were going to have to make changes anyway. It looks like they did not think there is enough demand. They fit now. That issue was resolved.

my only question is, can those car bellhousings from quicktime be made to work in a truck application? I mean the only difference is going to the mounting ears and the their bellhousing is a steel bellhousing. maybe bolt it up to the motor and the just get some 3/8 or 1/4" steel and form it and then just weld it to the bellhousing???? maybe the bellhousing needs to thicker because of the style mounting in the trucks????
