I stand corrected.

I was thinking the beginning was the end!

Re: 1963 Borg-Warner T-10 Date Codes

So.....my April 8, 1963 with a 3:36 non-posi should or should not have a transmission tag? If so, what should the tag read?

Thanks

Her's a pic of my stamp on a Feb 18, 1963 production date. I believe it to be a close ratio but tag is missing. I believe should be tagged R-R, S-S, or T-T according to NCRS pocket guide.

Re: 1963 Borg-Warner T-10 Date Codes

I have a similar thread that I started information seems conflicting. To answer your original question, yes you need a tag. At my last regional judging event the response was it just needs a tag rather than something specific. I have not read or seen a response that seems definitive on this subject.

Early 63 T10. I'll look for a later tag. I do believe they changes to all numbers on the tags on later T10's.

Re: 1963 Borg-Warner T-10 Date Codes

Well, I think I solved the dilemma of the data tag. I have attached three separate data pictures which indicates that my data tab on the tranny should be "QQ", I think.
1. In the specifications Chart, it shows a "QQ" should be used with the low gear of 2.54. However, it does state "early" cars and yet mine is an April car, which many consider "late".
2. Under the 1963 Power Team description, the 1st gear should be 2.54 for the 4 speed and the L75 300 HP
3. Also, in the Shop Manual it reads a low gear of 2.54.
4. So all indications are that if it does represent a 2.54 low gear, it should have a "QQ" data tag on the tranny.

Am I correct in my assumptions? Please see the attached pictures.

Yes, that looks correct. It appears we are the same. My car is 4th week of March 63 build.

Re: 1963 Borg-Warner T-10 Date Codes

Which vendor makes these data tags that state "QQ"?? But states for an "early car"

Would this tag be correct? CC claims to be correct prior to vin #12000.

Pic from Assembly Manual. Tag numbers in my previous reply matches the trans case number for RPO L76 - L-84. Did this replace the double letter tag code at some point? Or should this tag be on the trans in addition to a double letter code?

No.
As I posted years ago, there were different tags for 1963 close ratio T10s.

The speedometer drive gear (inside the trans) was different depending on which rear end ratio the trans was used with.
