Servo style vs Borg Warner style tranny

Recommended Posts

I'm trying to figure out if I have a servo style or Borg Warner style tranny without having to take it apart. I know you can look through the fill hole and try to determine that way but I was wondering if anyone knew the cut off date according to the serial number of the car. My serial number is SRL31107332. It's a 1969 2000 with matching numbers.

My info only goes far enough to show both types were used on the 2000.

 

Had this picture for ages. Its a Warner on the left and a Porsche on the right

I believe the supposed change over was around 9k or 10k. With the age of these cars, any more, the only way to know for sure is to look in the trany. As you alluded to, that can be accomplished by looking in the fill hole. No need to disassemble the transmission.

Look at the data tag on the transmission! The Brass synchro [borg Warner] is P/N 32010-A2550. The Steel synchro / servo [FS5C71A] is P/N 32010-25551. The NISMO optional gear ration sets were only to be installed on the steel synchro transmission.

The fill hole is usually half way up the side and hard to get your head up to. Drain it and look up from underneath?

Use an inspection mirror and light source or a video scope.

Can't believe I said this.... the counter shaft will be in the way. Fill hole it is.
