===Overdrive=== *Borg-Warner OD was available from early 1960 to '69; during 1970-'73 there wasn't one available. *Laycock-DeNormanville OD was available 1974-'76 but only for the Hornets and Gremlins with 150-T. *The OD could be had with column or floor shift. *The same Laycock-DeNormanville OD was also available in the Pacer for 1976. It was a column shift only. *British made Laycock-DeNormanville overdrive is the same as used in many MG and Triumph models. *The Borg Warner unit used a large electric solenoid to engage OD. The L-D unit has a sump and hydraulic pump similar to an automatic transmission. It worked similar to a 2-speed automatic, having 1:1 direct drive and overdrive. It has a sliding clutch assembly to engage OD instead of a band like used in an automatic transmission, or a locking pawl like used in the B-W units. *The T-89 also was used with OD in the V8 torque tube cars. *Borg-Warner overdrive case is 11-3/4" long (less torque tube adapter, if required). This includes the 1-1/2" thick adapter. *A complete T-96 w/OD is 18-3/4" long from front of case to end of tailshaft housing. The OD unit is the same for all. *The old style overdrive tranny is a manual, newer style has an automatic overdrive which shifts on 2nd and 3rd gear, almost like an automatic tranny. There is an electric kick-down to disengage OD. This switch is usually mounted on the accelerator linkage. *T-89 was fitted with a B-W overdrive unit on the rear. These didn't bolt to just any tranny, there was an adapter about an inch thick that went between the tranny and OD unit. The output shaft of the tranny was shorter and splined to fit the OD unit as well. *The [http://www.advanceadapters.com/downloads/saturn0.pdf Saturn overdrive] (originally produced by Warner) is a bolt on 0.75:1 overdrive for Jeeps equipped with the Dana 18 transfer case. <br>
