looking at buying a t-18

Buick, starter pocket on passenger side, Olds and Pontiac, starter on driver side. I can't remember which side Cadillac had the starter on but same bellhousing bolt pattern (472 and 500). That bellhousing looks to be an AA unit but not Buick specific. If you look close it's thicker in the transmission mounting area, i.e. no recesses and support webs. Also block mounting flange is thicker than standard BOP bellhousing.
Technically if the bellhousing has only the passenger side starter pocket it is Buick only, not BOP.

 

Actually, you'll need the planetary unit...it's the part with the splines in it. You can remove the planetary unit from the bowl gear pretty easily.

 

Terry and Nick. Thanks. Now I am slightly less confused. I have spent some time trying to sort this out when considering the T18 as a possibility behind my V6.

Now the $64,000 question… where can I find an inspection cover for same?

 

Spare time can be hard to come by.

I'll keep my eyes open for the inspection cover. Are there different designs, or are they all the same? I expect that a cover for an AA BH would be different that one for a BH with two starter pockets? Seems like I have a lot to learn to get this thing ready for installation/use.

 

I imagine you will have to custom fab an inspection cover to fit up to an AA bellhousing.

 

so should i pull the trigger on this set up or continue with the 465? what snags will i encounter with the t-18 versus sm465. like i said i was going to purchase the adapter from novak and found this for sale. it's a couple hours drive one way to pick it up. the guy said it was all bolted together in the cj2 but never ran. i can pick this up for the same cost as the novak adapter. i know the gearing is deeper in the 465 but not by much if this is in fact a 6:32:1 trans.

 

If I were you, I'd buy it - provided it checks out OK. I have been round and round on the tranny question, and if it has all the parts and they all work(together) you saves a bunch of money and time.

I ran a T18 in a Diesel F250 HD for many years. Tough transmission and never a bit of trouble with it.

 

For me the Difference between the 465 (175 lbs.) and the B&W T-18 ( 145 lbs) is really not much!..............everything Chuck mentioned above...yes. It will bolt up to a GM or BOP housing , but the large hole in the BOP housing has to be cut larger via a mill to accept it ............ratios 6.55 , 3.58, 1.57 & 1.0-1..........
.
The T-18's are in my eyes not more complex as long as you either stay with the Borg Warner "Jeep" version or the Borg Warner "Ford" version..........The Ford version is the much more acceptable version with an industry standard 6.5" input shaft stickout length.........ratios 6.32 , 3.09 , 1.69, & 1.0-1 The Ford version bearing collar has to be turned down a little on the OD but can be done on just about any lathe and perhaps a matching of two holes in the case to the type of housing being used.
It's when folks try to mix those two versions together that they have all the problems........There are some parts that do interchange, but no reason to even go there.
On Parts the Ford version T-18 is still fully supported.......the Jeep version is not , so some parts are scarce.
