ATL Cruiser
GOLD Star
1992 HZJ77 automatic A440F
GTurbo
PDI Intercooler
OEM boost compensator
This is possibly (likely) a dumb question, but it's been a LONG time since I've daily driven a truck from the 90's.
My 77 automatic is super sluggish on cold mornings. The engine is producing power fine (EGTS go straight up like normal). It just feels like I'm pulling a trailer load of bricks uphill. Once it's warmed up, all is well, and it snaps right along.
It never smokes ever. Fires right up always.
My initial thought was transmission fluid. But it's fresh, clean, and full. Possibly sticking boost compensator? EGTs climb great though.
Or maybe this is normal on a 1992 transmission. Would love to hear some thoughts.
