2>3 flare random
I have a 2 to 3 flare but it is not consistent
it flares ocassionally when hot and cold and throttle position seems to be irelevent i did k1 spring kit and no change i did vacuum adjust i did modulator adjust i did fluid/filter change i did bowden cable adjust nothing gets rid of the random flare it flares maybe 30 percent of the time with no pattern at all when it shifts correctly it shifts perfect, smooth crisp 1>2and 3>4 are always perfect 2>3 sometimes perfect other times flare i ordered the modulator pin when it comes in i will install it and post results if any any ideas? getting annoyed when i changed fluid there was no sludge in the pan and the fluid was red/not burnt no other issues Steve oh 1994 s350 3.5 603.971 722.4 i believe

What did you adjust and what is the current vacuum level at idle as measured in the line to the modulator?

What you want is to adjust the VCV to provide a much lower vacuum level at idle in a steady state condition. |

I delt with an identical random 2-3 shift issue several months ago. While installing the superior shift spring kit, discovered one of the old springs was broken. 3800 miles of perfect shifting so far. .

ok so the transmission saga continues
i had been sidetracked with front lower control arm bushings,i installed urethane by the way fairly easy job back to transmission the vacuum at idle is 12 if i tried getting it any lower by adjusting the vcv the throttle would begin to bind so i moved under the car to the modulator the modulator is the later type with a plastic lever style cap with the tee under it not the rubber cap type according to research the plastic cap is destroyed when removed but i pried it off carefully, turned the tee 1 and a half turns clockwise and snapped the cap back on all shifts are smooth at low throttle and with heavy throttle the shifts are nice and crisp but no bang thanks for your assistance, it is very appreciated sincerely----Steve 94 s350 w140

Great news. Glad the modulator adjustment worked for you. In the future, you really need to update the vehicle in your signature. Throughout this thread, I'm thinking you're referring to the '84 300SD, when, in reality, you were referring to the '94 S350. Although you stated it way at the bottom of the OP, I simply referred to the vehicle list in the signature for the diesel. |
