T-10 4-speed transmission for sale

[nut465gs]

I bought this 4-speed transmission several years ago from a friend who was getting out of Buicks. It was professionally rebuilt years ago and has been sitting on the shelf. I don't know much about it other than what info is marked on the case and tailshaft housing. Date code appears to be 1971. There are three rings on the input shaft. The transmission case and tailshaft housing are cast iron. $850

I can bring the transmission to Minneapolis this weekend for the 1st Annual Meeting of 65gs.com.

Thank you,
John

The trans you have is what is referred to as the 1st issue Super T-10.   They were designed as an over-the-counter replacement for the Muncie transmission when they quit making the Muncie.   The only production cars they came in were AMC's since they bought parts from GM for their cars.  Some have aluminum tail housings, and some have the cast iron one like this one does, but they are both the same layout as what came in the 65-66 GS.  There were several different gear sets available in these transmissions as well.  On the outside it looks like a mid-60s T10, but there are differences inside that make it stronger.

Brian,

As always, thanks for your valuable knowledge. I was hoping that you would add some more insight about this heavy beast of a transmission.

Brian (or others),

Do you know whether the shifter rods/linkage are the same for the T-10 as for the Muncie M21?

Looks like a real 65 T-10 case to me.
Correct 'T10-1B, W.G. Div, W-1' cast into the side,
Stamping on the top, 'WM3052'  breaks down as:
W= Borg Warner
M= December
30= 30th (of December)
5= 1965
2= 2nd shift.

Early units had an aluminum side cover, later ones were cast iron.

That cast iron tailshaft is very interesting. Was that used on the AMC's?


Muncie shifter can be used on a T-10, but shift levers on the Muncie are lower, don't know if rods will fit.
Car Craft did an article on installing a Hurst shifter into a '66 GS. Gives part numbers for shifter and rods if you decide to go Hurst.

3 grooves on the input shaft signifies the high-nickel, close-ratio gear set.

I had a 67 GS Hurst shifter (Muncie) rebuilt with the T-10 for my 66. It fit the T-10 with just a change in the reverse rod according to the rebuilder.  That shifter was not made any more back then, and is one of those unobtanium objects now. But, I am sure a universal Hurst shifter could be made to fit in the same way.

I think Car Craft used a 63 Impala Hurst shifter. Crash every once in a while has the 65-66 GS Hurst shifter for sale, I picked one up new in the box from him about 2 yeas ago. I still have the instructions from the box.

Rob (Robk) put a Hurst in his 65 convertible and bought an adapter so that he could use his original shifter handle.

Yeah, I discussed the adapter with Rob at our meet.  I think he said he got it from Brian?

So the entire original shifter is different for a T-10 and a Muncie?  I assumed the shifter was the same, but the rods might be different.  Sounds like most recommend a change to Hurst.  And I would like to keep the original shift handle. 

Hmmm.....

Believe this is what is needed for the shift handle. http://www.ss396.com/chevelle/FHB-64.html

The shifter mechanism is identical between Muncie and T10.  Shifter handle is the same too.  Linkage and shift levers are completely different. 
  If you go with a Hurst, be aware that you will have to tweak the opening in the hump in the floor slightly.  The head on the upper mounting bolt for the shifter mechanism will hit hard on the drivers side edge of the hole. 
   The adaptors to put stock handle on Hurst are available from places online, but be aware they raise the handle up some, so the flange where the handle bolts to the adaptor tends to tear the boots frequently.   
  The best solution I have seen is one I put in a friends car.  One of the Impala places sells a handle that looks just like a factory GM handle and takes the original shifter ball, but the bottom of it is made to bolt directly to a Hurst shifter.  The reverse lockout piece at the top is fake and all one piece with the handle, but you don't need it with a hurst anyway.  I had to tweak the angle of the handle a little at the bottom to get it shaped like a GS handle, but that was all hidden under the boot, so didn't have to have it chromed. 

[Robk]

If use the adapter that Dan showed with your factory shifter lever this is the linkage to use:  http://www.summitracing.com/parts/huu-3734734    The changes to the hump were very minimal.  Less than a half of an inch added to the hole.  Mine was repaired anyway so It didn't bother me.  I have been driving my car  a lot lately and I don't see any tension or wear on my boot.   It appears normal with lots of slack but I moved the ring a bit after I increased the hole size and that may be why i have no tension on the boot.  The lever itself in 1st gear sits a little higher than the Muncie but  if you are concerned about the original look when the car is sitting you can simply put it in neutral and use the parking brake or put it in second or fourth and it is down.

Now for the good:  I had burned through two Muncie shifters in 11,000 miles and I drive it easy,   I also rebuilt one of them once so really i trashed three.  With this adapter i have the original look and the performance doesn't compare.  No sloppy shifter, no missing gears, less rattle, etc. etc. etc.

This is the handle I was referring to above:
https://www.impalaparts.com/products/6467SHBH/1964-67-SHIFTER-HANDLE-HURST
As you can see, it bends toward the dash right at the bottom.  I cut about 3/4 of the way through it right at that bend, then bent it there to mimic a 65GS handle shape, then welded up the cut.  It was all below the boot when I was done.   Made a really neat, clean solution.

Here's the old Car Craft article on installing the Hurst onto a '66 GS:
http://www.hotrod.com/how-to/interior-electrical/116-0111-installing-hurst-transmission-shifter/

They used the Hurst Muncie shifter with the 60-63 full-size Chev (T-10) install kit.

I actually now own that 4 speed in the pictures. Bought the whole set up from Tony. Most of it now resides in my red '66, although I went with a Richmond 5 speed instead.
Sean from Paintworks in NH now owns Tony's old '66 GS vert that was featured in those articles.

Chuck,

I think if you had an original Buick T-10,you would have found the above to be true. That shifter was on the Borg-Warner trans,but it was made by Muncie. I guess the question is if the shifter you currently have was a Buick handle and was original to a GS. If that is the case and it fits the floor pan nice I would definitely reuse it. As far as it working on the Borg Warner trans,I do not foresee any real issue. I think there is enough adjustment to go either Muncie or T10 on the factory linkage.
