This is our 4L80E to TH400 Pilot Adapter/Spacer Kit. CNC Machined in House from 6061-T6 Billet Aluminum.
This adapter is used when replacing a TH400 with a 4L80E.
1979-1984 TH400 to Fig.8 NP205 will require a 2wd 4L80E. (Short 2wd 6-1/4" Stick-out requires the Output Shaft to be trimmed 1-1/8") (Long 2wd 7-5/8" Stick-out requires the Output Shaft to be trimmed 2-1/2")
1985-1991 TH400 to 6 Bolt Round NP205 will Require a 4wd 4L80E or a 2wd 4L80E with a 4wd Output Shaft. (No Output Shaft Modifications are Necessary)
All 2wd and some 4wd 4L80E have VSS Sensors built into the transmission. If your transmission does not have functional VSS Sensor we do sell a VSS Rear Output Kit for the NP205.
