No because this will not be the proper signal from manifold vacuum that tells the transmission what kind of throttle position and load the engine is under.
Yes, this really can happen. The transmission modulator ruptures and vacuum system system draws out trans fluid into engine oil thru vacuum pump into engine crankcase. Been there, done that. I replaced the modulator valve and dropped engine oil.
There are several causes that an automatic transmission will not want to shift into second gear. The two most common causes are transmission pump issues and trouble with the vacuum modulator.
The 1999 Monte Carlo has a 4T65E transmission that has no vacuum modulator, This transmission uses an EPC solenoid to control pressure, and commonly goes bad causing a harsh 1-2 upshift, pump whine and a check engine light with code P1811, max adapt.
My 84 D turbo has the lock vacuum pump in with the spare tire .
remove the transmission and torque converter. Remove the bolts from the pump (front of transmission case) and remove the pump.
Answer Because of differences in the vacuum characteristics of a turbo and non-turbo 300ZX the turbo models (Z31 seriers anyway) have a vacuum pump added under the front bumper that comes on when sufficient vacuum is not available from the engine for only the following....water solenoid for heater, ac/heater controls, cruise control.
pump and motor are up under front clip on passenger side
13 foot pounds
It is located at the front of the transmission, on the pump. You can see it on the pump were the torq converter goes into the transmission. The trans has to be pulled out of the car to do the repair.
You Can Have a Transmission Shop Run A Pressure Test. Good Luck
It provides the vacuum to operate the brake booster and the shift on the fly system.
vacuum pump in a diesel, is a pump installed to create vacuum to assist in opreation of brakes in pickups tha have diesel engines, the brakes are same as any other pickup and use vacuum created by the ngine to operate. a diesel engine does not create vacuum, as a gasoline engine does. that is why there is a vacuum pump added to a small diesel engine on f250 the pump is belt driven, is on the driver side of engine, under the a/c compressor.
