MONTE CARLO Transmission Tag Code 200R4 Monte Carlo SS 86-87

I need the 200r4 option code from a 86-87 monte carlo ss I think it was O Z from the plate

If I'm not mistaken, OZ is the Oldsmobile 442 H/O 200-4R code. CZ or CZF would be the Monte Carlo SS code.

OZ is 83-85 Oldsmobile VIN 9 cars only (this is the one you want, it shifts harder). KZF was the 86-87 442 transmissions and while similar, was a tad mushier in the shifts.

Chevy used what the same as Olds designators, except it started with a C instead of the O or K in the associated years, plus Monte SS rolled over their CZF to 88 as well.
