Authenticating a 70 GTO M-40 Transmission
Have a 70 GTO with a TH 400 transmission that has a PY 11259 tag. From what I've read the PY is the standard issue trans and the last numbers are the build date . (Please correct if this is wrong). The vin. # on the opposite side of trans is 70 J 120169.
The 69 are very lightly stamped. The vin tag on the car is 242370Z120169. So the J on the trans , clearly a J , should be a Z indicating a Fremont plant build. Has anyone come across this type of anomaly before? Thanks |

1970 PY eh. Not 1971? Black paint on tag?
If the Tag says 70 Py, then okay. The numbers stamped on the tag might infer an internal build code/sequence. Not sure if in infers a dated code. Tag still on the Case? Not PX, PD, PQ? Stencil still visible on the RH side of Bell HSG? 121 or 895 Front Pump Code? Internals can reveal a few tings about the level of 1970 vintage being intact. |
