Need Help Identifying C2(?) T-10

[Tom Spurgeon]

I need assistance. I purchased a transmission that is marked T-10. The gentleman said it fits a 1965 Corvette. However, the dimensions for the bell bousing mounts look different than I'm used to. As it sits on the floor (with mount toward the floor) the measurement across the bottom is app. 6 1/2 inches across, the mounting measurement across the top is app. 5 1/2 inches across, and the measurements from bottom to top are app. 7 1/2 inches. These are very different than the C1 T-10 that I'm used to. Also, the tail case is longer than the C1 T-10 I have. Can anyone help? Are these measurements correct for a 1965 fit? --- I bought it for parts, but am now undecided.
For any assistance --- THANK YOU !!!

Don't have one to "measure" to compare

but it sounds like you may have a Super T-10 - in any case, you need a MUNCIE, so communicate the markings on the trans, id it and what it fits and head for ebay.

Sounds like a Ford T-10

Borg Warner sold T-10 transmissions to just about all the car manufacturers during the sixties. I believe your case is designed to fit a Ford product. It is quite possible that some of the internal parts will still interchange with the GM models, however.

The assembly line 4-speeds installed in 1965 Corvettes were all made by Muncie, not B.W. Sorry.

Need Help Identifying T-10

Are there any letter codes on the tailshaft housing? Are there any mounting bosses for shifter on the tailshaft housing?

The "gentleman" that said that it would fit a 65 Corvette was not correct. As others have responded, all 1965 Corvettes originally used Muncie transmissions. While certain Borg-Warner T-10's would FIT a 1965 Corvette perfectly and function perfectly, not ALL B-W T-10's will so serve. This unit is one of the ones that won't.

Although the bellhousing mounting patterns are different for non-GM T-10's, one of the easiest ways to ID it is to measure the distance from the main case's front bellhousing mounting surface to the tip of the mainshaft. The following applies to this measurement:

GM applications, including all Chevrolet-----6.66"

most Ford small block applications-----------6.49"

most Ford big block applications-------------6.11"

Chrysler applications------------------------8.57"

Also, transmission length, as measured from the main case's bellhousing mounting surface to the very end of the extension housing, are different and can be used to further ID:

Ford and Chrysler----------------------------24.0"

most pre-71 GM applications------------------21.57"

most post-70 GM applications-----------------22.25"

Many internal parts of the Ford and Chrysler T-10's will interchange with the GM T-10's. However, the input shaft (gear) and mainshaft will not. The main case and extension housings obviously will not. I don't know if the side cover is interchangeable, or not.

Please report what you find as far as dimensions/ID goes.

Re: Thank you...It's Not Good

Thank you all for so much help. Here is some data: Body:T-10 / B-1 / W-1; Tail: T-10 / H-7 / K11 (?) 2. It measures 25 1/2 inches from mounting plate to tail end (w/o output). The distance from mounting plate to the tip of the input shaft appears to be 6 3/4 inches. The smaller numbers on the main case seem to be destroyed. A friend who previously rebuilt GM transmissions during the sixties and early seventies relayed the same thoughts. Although his knowledge of Ford is not as detailed, he was confident it's a Ford. Upon cleaning and closer inspection, he found the carrier plate was aluminum, while the transmission itself is cast iron. He also pointed out that the side cover plate is aluminum dated 12-12-62. As I already purchased the unit on ebay, I'm going to contact ebay Monday with this information. If I can find resolve with the seller, it won't be an issue. If not, I purchased it for parts -maybe I can use some ---Thanks again for the help! (Be careful what you by on ebay...one photo and a promise may not be enough)

Tom----

It could well be a Ford unit, but I'm surprised that it doesn't match any of the dimensions that I described for a Ford. Perhaps Ford had more configurations than I'm aware of; my Ford knowledge and informational resources are not extensive. In any event, GM was not using any cast iron T-10s by late 1962 when this unit was made. Also, for a 1962 build GM unit, the length would definitely have been the 21.57" that I mentioned.

There's another possibility, though. I think that T-10s were also used in some AMC vehicles, although I don't know if any were being used as early as the 1963 model year that this one would have been built for. I don't have any specs on the AMC transmissions.

What was the eBay item number? *NM*

[Tom Spurgeon]

The Number Was...

Dave,
The item number was 2429149948.
Thanks,
Tom

[Dave Suesz]

I can tell you what it's not...

is a Ford trans. Ford tranmissions of this era had the shifter mounted on the tailshaft housing via three bosses, which this trans lacks.
