Question about 1999 Chevrolet Silverado 1500

Open Question

I have a 1993 K1500, 305, Auto with the electronic automatic overdrive tranny, that has some issues. a few months ago, it started shifting out of overdrive when slight pressure was applied to the throttle. Shifts fine through the gears, and even solidly into overdrive. After cruising speed is attained, and you let off the throttle, then re apply throttle to it gently, it is either slipping or shifts into neutral. hit the throttle hard, and it downshifts, picks up speed and shifts back fine. Any ideas? I also have charging system issues driving me batty too. Might this be part of the problem?

    is all this taking place right at the speed where it shifts into overdrive or way beyond?

Overdrive Control Switch
The overdrive control switch is located in the instrument
panel. In the On position, automatic shifts
into fourth gear overdrive will occur. In the Off position,
the switch overrides the powertrain control module
preventing a shift to overdrive fourth gear range.
The switch has an indicator light that illuminates
when overdrive is turned off. The switch also resets
when the ignition key is turned to the OFF position
so that the automatic overdrive feature is restored.
The use of fault codes is employed to help diagnose
the electronic components that operate the overdrive
unit and torque converter clutch.

you may have a Thottle position sensor issue, a Manual Lever Positioning sensor issue, or possibly an overdrive sprag issue, i drive a 93 Lightning, so these issues are commonly found on our truck which are very similar...check these parts, especially the Manual Lever Positioning sensor, then if that does not solve the issue try going to a transmission shop

I have a 1991 Volvo 740 w/an automatic transmission.A couple of months ago the overdrive indicator ( red arrow ) started to turn on and it doesn't turn off when I press the button. When I drive, it seems...


It may be a faulty relay - usually behind the radio - it makes a clicking sound when you hit the button on the shift lever. Or it may be the overdrive solinoid which is mounted on the top of the tranny. Check all of your connestions first. One other thing - the wire from the shift lever overdrive button to the overdrive solenoid on the tranny may run over the top of the drive shaft - check for wear

IT IS NOT GOING INTO NEUTRAL. IT HAS LOST THE DIRECT DRIVE CLUTCH PACK INTERNALLY. SOUNDS LIKE IT IS HIGH MILEAGE. IF SO AND YOU CHANGE THE FLUID IT CLEANS UP ALL THE VARNISH IN THE TRANNY AND THE END RESULT IS TRANNY MALFUNCTIONS DEPENDING ON WHAT KIND OF CARE IT HAS HAD IN THE PAST.
