shared B-body code, cited from the Chevrolet Caprice kit; matched to the Custom Cruiser by meaning only: Wikipedia's Custom Cruiser article names the THM 200-4R 4 speed overdrive automatic through 1990 but prints no code, and the kit prints MX0 (the 1984, 1986, 1987 and 1988 pages print MXO) for the Caprice wagon among other models; 1983 is left out because the 1983 Caprice kit shows the overdrive automatic without a code, and 1989 because the 1989 kit's listed pages do not print it

the ordering code for the 440-T4 unit; the cited kit pages print MXO (letter O); the zero form is the code; matched to the unit by meaning: Wikipedia's Ciera article names the 4 speed automatic from 1984 but prints no code; shared A-body code; cited from the Chevrolet Celebrity kits

- 1984–1985 Factory-verified
shared B-body transmission code, cited from the Chevrolet Caprice kits (the 1984 page prints MXO); Wikipedia names the THM 200-4R four-speed overdrive automatic among the generation's transmissions, while the kits pair MX0 with the 700-R4 (1985) and with the 700-R4 or the 200-4R (1984), so the code is matched to the Delta 88 by its meaning, a 4 speed overdrive automatic, not by one unit; the 1983 Caprice kit shows the overdrive automatic without a code, so 1983 is left out
