Really SLOW acceleration under D

djalkyd · 02-17-2006, 03:00 AM

shift solenoids may not be the problem. it sounds to me like the manual valve is sticking or the 1-2 or 2-3 shift valve in the valve body. it could also be a stuck checkball to where you are not getting fluid flow to those valves for that shift.

now you say you have 1st and 2nd manual but not 3rd or overdrive. it could be an over running clutch or an actual clutch pack itself. how did the tranny fluid look and smell? if it is dark brown and smells burnt then the clutch packs could be going out.

can you rev it high in D but not get any movement? if so then the clutches are going bad or an actual over running clutch and bearing is going bad. then you would need a rebuild.

if it is the manual valve, try and adjust the manual linkage from the shifter to the tranny and see if you get more movement out of it.

try flushing the tranny first and go from there.

I have a 89 Turbo Auto. i had the same problem is feels like the car is starting of in maybe 3rd gear replace the shift solenoids and fix the problem. i do not remeber exactly which ones was bad. But the solenoid cost me about 115 dollars at the dealer. They use a on off pattern to shift so if they both go bad then it is a fail safe to stay in 3rd gear. It almost felt like you have the e brake on or something its so bad. also you pull it down in first gear manually it dpes better but still didnt seem to have the power it should have./

did the solenoids fix the problem or is it still acting up?
