#355035 - 06/22/09 07:13 PM 727 ID and Q's...

Okayyy... I finally got around to grabbing a trans out of storage for a long awaited rebuild.

I need to ID this Trans/Valvebody before I go spending money I don't have on parts that won't work.

I only found a few numbers stamped on the pan rail and a few casting numbers on the case.

I was hoping someone could decode it and maybe answer a few Q's.

The previous owner said it came out of his 68 charger.

Trans Case Pan rail: G2538334 2425030

Part number: 2466900 on main case body, 2466901 on tail shaft.

There were also some box type date codes but the case is still a little too dirty to ID those (started with 65 and had dots into 9 or 10 of the boxes).

There was no valvebody with that trans when I bought it (previous owner was keeping it).

Can I use any valvebody I want or does each trans use particular valvebodies?

I also have a valvebody from a smallblock 727, will that VB work in the trans I am trying to ID?

Here are the numbers from that smallblock 727 VB...

Part # on top side of VB: 3410925 (has wheel type date code 06/1971)

Part # on bottom side of VB: 3410435

Number stamped on separator plate: 10225/1000041

I also plan to use a Trans-go TF2 if that makes a difference with the valvebody choice.

Last Q... what's the best rebuild/master rebuild kit with the best parts for the money? who's the best to shop with?
I plan to put this trans behind a mild 440, have no idea how many hp but I'm sure will produce way, way, wayyy less than 600hp.

The trans is a 66 originally for a 361/383.

I have the same one. Remember that 66 has the course spline as opposed to 67-later fine spline if you are going with an aftermarket TC.

Also first year for external shift lever.
Will only have 3 pinion planetaries.
Old style rear servo piston.
Original VB has a restrictor orifice that delays manual 1-2 upshift. But that doesnt matter cuz you dont have original VB.

I really am not sure if you can use that other VB with this tranny.

Somebody will chime in to answer that one tho.

The valve body with the steel separator plate stamped 10225/1000041 is probably gold colored from a B&M Shift Improver kit. This plate might not be compatible with the TF-2 kit so you'd be better off to get an untouched VB.

For a '66 trans you would want a '66-70 VB but a '71-'73 will work.

Makco is a good source for quality rebuild parts at good prices.
I'm supposed to respect my elders, but its getting harder and harder for me to find one now.
