Higher-shift point and stronger bands & springs.I believe a thicker shaft as well? *TH400 CW Trans. was coded for the L78 Chevelle-Nova-Camaro,& LT-1 Camaro-Nova. *TH400 CR & CS Trans. was coded for the LS5 Chevelle-Monte Carlo,& Corvette w/Transitorizied Ignition. *TH400 CF Trans. was coded for the L34 Chevelle-Camaro-Nova. *TH400 CK Trans. was coded for the 300HP 350cid Corvette. -------------------- Post Extras:       YENKO DEUCE REGISTRY Reged: 04/27/00 Posts: 10255 Loc: PA Re: CY & CX 400THM: differences & similarities [Re: Mr70]       #109881 - 12/09/04 11:07 PM Edit   Reply   Quote   Quick Reply   Chuck, the comparison is between the CX vs. the CY, not the CW version.
