Topic: Spring 65 San Jose Borg-Warner T-10 Usage?

[steve_f]

My car has a T-ten B/W transmission with the 4 speed shifter, rods, tabs and Ford shifter with reverse lock out.  In a previous discussion I learned that the HEH-BT close ratio trans is the assembly line part correct for my May of 65 San Jose GT.  I also learned that the present shifter, rods and tabs would need to be replaced ?  Looking for some help with that.  My shift lever with reverse lock out finger pull should swap to another shifter body OK ?  The Ford shifter bodies usually have no identifying numbers or marks but are all the same up to 68 ?  Do the Ford rods and tabs carry any identifying numbers or marks ?   Thanks for any help with this.  Brian

Brian,
I'm curious why you believe that your car should have a different transmission. My May 65 SJ GT Fastback has the Borg-Warner T-10 transmission. If I remember right, mine has the same date code stamping as yours.

Steve I don't believe my car should have a different transmission.  I asked the ' originality ' question here because it is the best online forum to ask that type of question.  All the resources I checked stated a FORD toploader would have been the assembly line transmission.  None stated a T-10 would be correct for a 65 GT.  You responded to my question, as well as several others, back in 2015 and shared your info.  This Forum may have the only record of assembly line B/W T-10's being installed in 65 Mustangs ?    Brian

Brian,
The MPC shows the HEK-V Borg-Warner 4 speed on 1965 289s on in section 70 page 6. What other information says that the Borg-Warner should not be in your car?  Just curious as I believe mine is the original transmission to my car.

To answer your question; the 2015 conversation, Charles's comment, and the dates provided on the MPC page for the HEK-V and HEH-BT Transmissions raise some question.  The dates suggest the HEH-BT would be the more appropriate trans.  To be clear I did initially misidentify my T-10 as a 'close ratio ' later to learn that it is a ' wide ratio '.  Thanks Brian  http://www.concoursmustang.com/forum/index.php?topic=12091.msg73280#msg73280

Brian,
I remember the initial thread discussion. I do find it more than a coincidence that two 1965 SJ GT Fastbacks with scheduled build days 14 days apart have identical Borg-Warner transmissions that should have been Ford Toploaders. Maybe this is one for Jeff's San Jose differences list. Jeff or Charles?

Ford documents being incorrect.  Might have happened. Have you guys found the assembly dates on your trans?  Just another data point.

Guess I can look through my pictures to see if we have any other San Jose examples around the same time

Easy to see that we've gotten off of the subject of shifters so will be splitting this conversation off to its own

Jeff,
One of the pictures I posted here is the date stamp on my transmission.

C245 2

When decoded based on the earlier thread I believe that's March 24, 1965 second shift. Please correct me if I'm wrong on that.
Thanks.

Jeff,
In Brian's original 2015 thread there was another person, petersixtfive, who posted a pic of the date code for his T-10 from his June 65 SJ GT Fastback. It was a May 25, 1965 shift 1 date.
I know this is a VERY small sample and not statistically significant , but all three cars are SJ GT fastbacks.

In the quest for more data, can people with a spring (or summer) 1965 SJ factory 4 speed car chime in with your car's expected build date and whether or not it is a Borg-Warner T-10 or Ford Toploader transmission. Please include the transmission date code if you have it.
Thanks.

Thanks for mentioning that in this newly separated thread. We've often sort of agreed that three examples is sort of the starting point for a discussion and a start for some additional effort when plant and time period all kind of match. Lets see where this one takes us.

Did check my picture collection of cars and unfortunately have nothing to add to the effort at this time from that time period. Often don't have allot of undercarriage pictures of completely assembled cars and so few were manual cars. Only found one picture so far of a -V t-10 but it came out of a different car (late 66 San Jose) - likely something that someone swap in over time

That person would be me
Just confirming again that the T10 transmission was original to the car as was the std bore engine

For reference
The date numbers from the T10 4 speed in my 65 GT
E255 1
May 25th 1965
Shift1

Thanks Peter.
Do you have the projected June build date for your car? Trying to create a build window for these cars.
Thanks.
Steve
