1988 trans (904) is the converter lockup control, pressure apply-spring release, or spring apply-pressure release. Strickly hydraulic control, not electric. Thanks
Hi Charrlie_S,
First of all just wanted to say thanks for always sharing your knowledge on A/C and slant6 engines with all of us on FABO. Always enjoy reading your posts on those subject areas. Concerning your question on lockup’s... I have a 1983 A998 hydraulic lockup in my 318 1973 Dart Swinger and it works great, mine’s just a cruiser. Chrysler started using RH (hydraulic) lockup’s in 1978 and continued until 1985....in 1986 changeover was made to RE (electronic lockup’s). There’s a great article at allpar.com concerning lockup’s history. Hope this helps...thanks again for all your help to everyone.
Take Care,
Greg
