Best Answer

I assume your refering to the vacuum modulator which controls transmission shift points. Remove the vacuum hose from the modulator. Using a small screwdriver, turn the screw inside the modulator. It may take several tries to get it right.

How do you adjust a 350 trany?

There is no adjustments to a 350 Turbo Transmission (GM). The only external thing that would cause shift problems is the vacuum modulator on the side. This is replaceable easily. Check for proper vacuum signal to the modulator. Make sure there are no holes and or kinks in the vacuum line from the engine to the modulator. If none is found, replace the modulator for shift complaints. If it is slipping, the tranmission will require removal and overhaul. This transmission uses wet clutch plates and automatically compensates for wear in the plates to a certain point.
