T10 transmission identification

[Christer Arakangas]

Hi,

I'm restoring my 1962 Corvette, and am now investigating the transmission. I'm pretty sure it's not original. The tailshaft is marked 10K-7 and has a casting date of 12-30-65. In the august issue of Corvette Fever there's an article about the T10 transmission. Reading this I can determine that it at least looks like a T10-7B tailshaft (supposedly used in '60 trough '61). But what about the casting date?

The gear case is marked T10-1B and has an additional casting information of "C7". Close to the side cover there are some stamped information: WD1262.

Does anyone know what all this means? Is it a Corvette transmission at all? By the way, there's a name etched on the housing: "Brian Chauncey". Maybe somone out there knows who that is. The gear box probably belonged to him once.

Best Regards,

Re: T10 transmission identification

you will need to find a 62 date coded tail housing as what you have isn't orig. as far as the main case data you supplied goes, The WD means warner gear division, the mfgr. I stands for the month, sept in this case .26 is the twenty sixth day of the month and the 2 is calander year 62. for this main case to work in your vet , the vet would have had to be built after sept 26, 1962. since the last 62s rolled of the line in ST. Louis in August of 62, the main case can't be original. Look for a main case dated 2 to 6 months b/4 the 62 was built. You'll also need the proper date coded tail housing and shifter plate. the gears in your existing case will fit the pieces you'll be buying. good luck, mike

Also, be aware that transmission "numbers" aren't judged in Flight Judging - just appearance and configuration.

Mike,
Maybe I'm having a senior moment, but I have an entirely different take on his trans.
First, it's a T10-1B case, which is iron, and not correct for any '62 Vette. It should be a T10-1C (alum) (or possibly, if late, a T10-D?)
I believe only the "W" in the stamping indicates Warner Gear Div.. The "D" is the month code for April. I don't believe they stamped "I"s because they were confused with "1"s. Stampings go to "M" for Dec. rather than ending with "L".
Warner gear also stamped the shift as the last digit.
Therefore, I believe this trans is
W: Warner gear
D: April
12: 12th of April
6: 1966
2: second shift

The cast"C7" (March 7th?) would fit an April assembly. I'd say it's a Service Parts case.
Maybe I'm out to lunch, but that would be my interpretation.

Re: T10 transmission identification

You are correct Verne, a '62 used a T10-1C aluminum case and single mount tailhousing.

I think you've left out a number in your

WD stamping, unless they had quit marking the # of the shift by 1966 - during the years of production use, the last digit was 1, 2 or 3 - dependent on which shift had assembled it.
