That will be nice with the electric lock-up. The earlier lock-up a999 are hydraulic and were some what troublesome for Chrysler. Mine is in a 83 grand fury. Not sure what it is for sure but I"m hoping it does not have the lock up but it is unlikely it doesn't. Its a cop car so maybe. Fender tag says it has a a999. Wont know if it locks up till I pull the converter I guess.
