http://en.wikipedia.org/wiki/Turbo-Hydramatic#THM200-4R The early 200-4r's suffered from a weak sunshell that was prone to breaking. The non performance ones also have a low rpm shift. The later units are much better, and GM did updates to correct the early problems. The performance ones were in thr GN's, Monte Carlo SS, Hurst Olds. They have a shift point of 5800 RPM. You can id them by the metal tag on the trans.

KZF ** Olds 442/Hurst
CZF ** Monte SS
BRF ** GN/T-Type/Turbo Regals
OZ ** Hurst Olds
OM Olds 350 Diesels
OG Olds 307
BY V-6 252 Cars
AA and AP Cadillac's

1-2 shift points where not the same for all the performance versions of the 200-4R. The Monte Carlo version (CZ code) has the highest factory 1-2 shift point.
