I need a replacement (used) trannie. I can buy a CZF for $250 or a BRF for $550; both have about the same miles ~ 50K and both are 87s. Which should I buy? Three hundred dollars would buy a lot of upgraded parts.
I know the servo is different--last two digits are 92 for CZF versus 94 for BRF--but apparently even owners of BRFs upgrade to the PTS-type larger diameter servos. By the way, is that 36% larger than stock BRF?
I know that the govenors look identical except that the CZF has two springs. If the "extra" spring is simply removed will the shifts come to around 5500 RPM?
I guess the key question is are the valve bodies identical or nearly identical and does anyone have the information/parts to make a CZF valve body equivalent to a BRF?
Is it reasonably good odds to install a trannie with 50k or should I spring for a rebuild? A local trannie guy says he can do a freshen up for $500.
