Jim SNIP Hi guys... 1. Does a 75 258 Pacer have a lockup tranny..... 2. I have a 76 258 with auto attached....not sure what it came out of....will it fit...is it a lockup Thanks, Jim SNIP The engine transmission combinations in a Pacer are exactly the same as used in all other AMC cars. Thus they will interchange. The Lock Up Torque Converter packages in the 904 transmission that is the transmission used with the I-6 engines was first used in 1980. Even then, if you had a 1980 transmission it would bolt up to your 1975 or 1976 engine exactly correct and bolt into your car. For example, I am using a 1975 Pacer 258 engine, a 1980 Spirit Lock Up Torque Converter 904 and the MOPAR Fuel Injection conversion designed for Jeep applications from 1981 and newer in my 1980 Spirit. It all bolts up, fits and passes smog. The only physical differences that I see is the longer oil dip stick, the metal heater hose from the Pacer which I kept 'cause I though it was cool and looked good and one heat shield that was on the 1980 engine that protected the drivers side back cts that was screwed into the block from exhaust heat did not have a fitting on the 1975 engine, so I left it off. Also the Pacer Motor Mounts were removed and Spirit Motor mounts installed. SNIP the only new thing should be the lockup switch. (Andrew) Snip Andrew, sorry, but what do you mean by this, are you referring to some kind of a physical switch? Or are you referring to the fact that the gearing is lower in first and second and that the lock up function would be present?
