T-56 floor pan mods?

Hello all, I have a 1966 2 door post belair. I am interested in putting a t-56 in it. Has anyone done this? How much modification is required to the floor pan? Would the bench seat still work? The car is currently a 4-speed car.

Thanks.

If you have not purchased a tranny yet the fine folks that make the T-56 (Tremec) now sell a T-56 designed to fit an older muscle car (called a TKO) so that you do not have to cut up the transmission tunnel. (this is based upon their print ads as I have no personal experience).

It won't require any mods IF you don't run the reverse lock out solenoid. If you do, you just need to get angry with a ball peen hammer for a couple of minutes. No need to cut and weld.

Two doors, four doors, wagons, and ragtops.

I thought the TKOs were only five speeds?

Do you have pictures of the "modification" jay?

They have a couple of new designs (which I thought where also called TKO's instead of the old "T" letter that Borg-Warner, who created and made the transmission's originally), Maybe the lettering system include the the "K" for Kessler, but whatever the O stands for I have no idea (from my memory Kessler bought out Borg-Warner's design and rights to the tranny who was then bought out by Tremec if I am keeping that straight in my mind). It all may just be a marketing ploy.

Because most old cars have sloping trans tunnels they aledgedly did something to the bolt on tail housing design to center the shifter in same place as the old Muncie-Hurst shifter location and dropped the profile in the back of the trans to keep you from carving up your floor boards to make the unit fit older cars and at the same time use a mechanical speedo gear.

Unless something has recently changed, you are correct on that point James.

Yes, the TKO is completely different than the Tremec (formerly Borg-Warner) T56.

I don't have a pic of the floor pan dimple required, but if you look at the location of the reverse lockout solenoid, it will be obvious. To eliminate that issue, I simply removed the solenoid and replaced with a block out plate.

See the thing pointing towards the front with the electrical connector? That's the reverse lockout.
