What transmissions for a 65
Posted by: vwbusman66 ()

A guy local to me has an EM (61-63) 4 speed for cheap.

I know the differential won't work with the suspension, but will the 4 speed?
What is needed, besides the speedometer drive in the wheel and associated cross member, to put a 66-69 4 speed in a 65?

You can easily install a '61-3 trans in a '65 as long as you have the "0ne-year-only" 1965 differential. (two bolts per side between trans and diff)

'65 diff
61-3 input shaft
Change seal in diff snout to smaller 61-3 size
Transmission support for '65 4-sp
Change reverse light switch setup
Adjust shift rod length (maybe)

No change needed in speedometer

Your signature says '66 though. Did you mean to write '66 and not '65?

I typed it right. This would be for a 65.
I suppose a real upgrade would be the 66-69 4 speed.
What do I need to do to put a 66-69 in a 65?

What do I need to do to put a 66-69 in a 65?

Craig replies:
Complete 66-9 transaxle with U-joint straps
66-9 MT trans support
66-9 MT shift tube stabilizer
66-9 reverse switch connector and pigtail (or complete 66-9 mid-body harness)
Adjust shift coupler (to make shorter and allow for longer trans)


Arguably, the best trans for a '65 is a '64-65 4-sp. Very sweet shifting and nice ratios. The '66-9 4-sp is a bit of a compromise.

66-69 is the choice if you are going racing.
They are stronger, but do not shift as smoothly as a 64-65 box as Craig stated.
The 66-69 3.11 first gear is also less than idea for the low torque Corvair engine.....in a perfect world it would have been a 3.50 first gear like later 4 cylinder Saginaws had.
The 64-65 car 4 speed has a slightly better 3.20 first gear.
The 61-63 AND 64-65 FC had the 3.65 first gear which IMHO is the best one of the mass produced 4 speeds. Many guys look for the 64-65 FC because it has the 3.65 first gear but with all the internal improvements that the 64-65 car 4 speed had.
Modern cars now all have very low first gears........even automatic transmissions which is a big help for getting a car out of the hole when you don't have a lot of torque.

James:

If you need a 65 4 speed, we can trade one or 2 I have. Let me know.

Both have differentials on them.

The best parts for these cars are the ones the engineers had put in IMO.
My favorite trannies for my Corvairs (pretty much in order) are:
The bulletproof PG (" a broken PG is a rare PG")
The 66-69 3 speed (so easy to find R and less shifting- I am quoting my wife)
The 64-65 4 speed (so smooth and easy to shift)
