What years did these tranny come out in the cjs? I am looking at 2 cjs both 83s and the guy says they both have T18s .... I'm calling BS ... but don't know for sure and haven't had a cance to get the casting #s
this guy said that both jeeps were completely stock ... nothing had been swapped, I didn't know if the t-18s were avaiable in 83 ... didn't think so, but don't know? and would like to know what they are before going ahead with the deal???
85 CJ7, AMC 20, welded and trussed, Superior 1pc axles, Dana 30 Superwinch hubs, 4:10 gears Detroits front and rear. New 258 with MC2150, TFI. 4" Superlift suspension, 1" Prothane body, Herculiner inside and underneath. OBA with front and rear custom bumpers for tanks. All rolling on 33's.
The T-18 was optional on CJs from 1971-1979. The T-18A version used from 1977-1979 is the best transmission ever put in a CJ by the factory since it features a granny low first gear(6:32:1.) Earlier T-18s have the same great strength, but a 4.03:1 first. The T-98 is the predecessor to the T-18 that was an option for CJs from 1955-1970.
Other Jeep trucks also had the T-98 as an option from 1955-1970, the close ratio T-18 optional from 1971-1975, and the wide ratio T-18 from 1976-1979. After 1979, the wide ratio T-18 was only avilable as an option in the J-20 pickup truck from 1980-1981. This version of the T-18 has the round New Process bolt pattern and 23 spline output, but the adapter is long for a short wheel base Jeep. Earlier T-18s and T-98s used the "Texas" bolt pattern and 6 spline output. The truck version of the T-18 uses a long input shaft compared to the T-98 or CJ T-18s.
