Hi, I’m planning on converting my 2 speed power glide to a 4 speed super T10 in my 66 Caprice.
Just wondering if I need to change the cross member and anything else that could help.
Thanks in advance

Brad Lenz

Check out the “Automatic to 4 speed” article in the clutch/transmission section of the “Reference Section” above. It’s a good place to start.

it is and aint as easy as it sounds. you can just get parts and slap um together as is often done.
or you can get as technical as you want.
as i see it, transmission to engine alignment is very important and slapping parts together is just that. dialing in a bellhousing so that the trans is aligned to the engine is very time consuming but i feel is well worth it. there is up-down, left-right, and angles up-down, left-right to consider or not. i would try to get the bellhousing milled so that the two faces are parallell for a start. that will help or cure the angles issue. the left,right,up,down will need to be done with dowel pins. overkill? maybe. am i nuts? for sure. you decide what you want.

70 L camino, grampa engine, g-force 5 spd, road rage suspension. Pray first before all else fails.

Here's a couple of links you may find helpful:

And here's one vender I've bought parts from that has met my standards:

Glad to see ANY manual transmission installations.

I swapped my '65 Impala from PG to T10 and was able to use the original crossmember but I did have to elongate the transmission mount slots slightly.

You should be able to use the same crossmember.

Here is where I am at with my conversion:

With regards to using a Super T10 in a 66 (or 67), your shifter set up may require some additional conversion info.

I am pretty sure if you use a Hurst shifter with the Muncie trans, you need a 4205 (I think) mounting plate.

Does anyone know if the 4205 plate is also used for a Super T10, or do you need to fab one Or use another numbered plate? Input please someone?

I'm thinking of going with a ST10 in the future as well instead of using the Saginaw and because Muncies are getting pricey. ST10 is a good option and good trans.

Sorry OP, no intention to hijack your thread. But shifter issues always seem to come up with B bodies. I think someone on this board put an ST10 behind big block '66. Maybe he'll chime in.

Thank you aghaga. So if I understand correctly, 4205 mounting plate for hurst shifter for either Saginaw, Muncie or BW ST10. Then You just need to get the correct shifter arms for the tranny used?

I believe the Hurst installation 'kit' (the correct one for the transmission) includes what is required.

Attached is one for a Muncie.

Thanks for that attachment Pete. I wonder if there is one for a Hurst Saginaw setup. Probably not huge demand, but most small block 4 speed cars from what I’m aware came with a Sag. So hurst must have made a kit you’d think. Never seen it discussed.

Hurst certainly used to provide the installation kit for the 4 speed Saginaw. I have not looked for one in years.

As for 4 speed Saginaws for 'most' sbc? I'm not a historian but I believe in the full size Chevy's (thru '66, or maybe even later), the 4 speeds were either BW (before early '63) or Muncie (after early '63).

Chevelle, Camaro, Chevy II, Vega were more readily available with the Saginaw 4 speed.

Here's another attachment with some useful info.
