Customer Question

I have a 1997 chevy venture .recently the tranny went out. so I replaced it with a used one . I replaced the converter seal,and both axel seals . and the fluid and filter. it worked flawless for 3 weeks. but now when I come to a stop sign and go to take off it sometimes doesn't take off until the rpm's come up to about 1500 to 2000. and then boom it will take off and shift perfect. no slipping at all . I also had this happen 1 time when shifted into reverse. any idea's ? thanks Terry.

are there any codes at all set in the computer ?

Customer: replied 8 months ago.
no codes
Expert:  Gary replied 8 months ago.

how often will it act up and do this ?

Customer: replied 8 months ago.
not every but almost
Expert:  Gary replied 8 months ago.

99 % of these doing this are usually dirty or bad pressure control solenoids in the transmissions valve body

have you tired a transmission flush yet with a flush machine ?

Customer: replied 8 months ago.
no not yet . but when I changed the pan gasket and filter the inside of the pan looked clean and the old fluid looked pink and didn't smell burnt.
Expert:  Gary replied 8 months ago.

fine small debris can built up in the pressure control screen and cause this

have it flushed good with a flush machine if it still acts up the transmissions side cover would need to come off to remove and clean the valve body and to replace the pressure control solenoid in the valve body

did you ohm the other solenoids?

Customer: replied 8 months ago.
no I did not. whats the spec for them ? is it possible to check them in car ?
Expert:  JOHN aka Eauto replied 8 months ago.

no they need removal

also it could be broken servo piston something is causing a pressure drop

Customer: replied 8 months ago.
where is that located ? and what should the ohms be for all the solenoids ?
Expert:  JOHN aka Eauto replied 8 months ago.

in the valve body

To test a solenoid all you need is a hand held ohm meter. Connect the two wires coming off the solenoid to the two leads on the ohm meter. A properly working solenoid should return a reading of around 20 – 30 ohms of resistance. If no reading is returned, you can assume the wire is broken.
