How many solenoids does the 4160e in a 94 z28 have? I am having issues and a mechanic told me it might be one of the solenoids. When cold, it revs higher than usual, but does not rev higher than 3000 rpm. And seems like its not shifting. At idle seems to be fine. Release of the throttle causes rpm to drop as if at idle. After running for about 30 mins, i park and turn off the car. Turn it back on and seems to be back to normal . But i have noticed loss of power and torque when it is shifting properly. Car has 98,500 miles. If a solenoid, which one can it be, or what other issue might it have?????? Appreciate any input... Thanks in advance

 

Sounds like it might be a shift solenoid. There are 2 shift solenoids near the tail of the trans, one pressure solenoid, and a 3-2 downshift solenoid near the front.

 

I would try changing the 1-2 and 2-3 shift solenoids at the rear of the trans they are like 25 dollars each and service the filter at the same time.

 

thanks i appreciate the input. what has to be done in order to replace the 2 shift solenoids??? is is an easy job?

 

Depends on which way the clips are in. Pull the pan and see.

 

Yes actually its very simple and no more complicated than replacing the filter

 

This is the first car that i am really goin to dig my hands into... I have never changed out the tranny oil filter. How would i go about doin that??? Thanks again
