SOURCE: 1982 G30 Chevy Van power steering fluid

Find the power steering pump. The fluid goes in the top of the pump. Look for a twist off cap that has a measuring stick attached to the under side, when you take it off. Make sure you use the correct type of fuild for YOUR kind of vehicle. There are diffrent types for different makes of vehicles. Don't OVERFILL the pump.

If vehicle was left outside or in an unheated garage, there is a strong possibility that condensation has contaminated your fuel. Easiest way to check is to remove fuel filter and pour contents into a glass jar. If you see two different layers of liquid in the jar, the bottom part is water. Replace with new filter and drop the tank. Remove sending unit. pour contents into a large container and clean out inside with clean dry rags. Remember, fuel is dangerous to work with and fumes travel pretty far on the ground. So, no open flames electrical stuff, cigarettes etc for a good perimeter around work area. Generally, you can re-use top 3/4 of fuel you removed by syphon. Don't use remainder in your vehicle. Part can be used for lawnmower etc as long as you only take the part above the water line.

That does sound like a linkage adjustment problem.

If that does not work, I'd try a fluid change and filter. But your diagnostics with pulling on the gear shifter is a pretty good indication of a linkage problem.

SOURCE: i have a chevy 93 astro van my transmission won't

If the van is an all power, Have your alternator checked. DO NOT remove battery cable while running to check alternator. You definitely will need a new one then. they are sensitive to voltage changes, if voltage drops much will lock auto trans in 1st gear & various others things will stop working that draw much juice. Anything under 11.7 volts will trigger trans lock into gear on these vans. Autozone & O'Reillys checks them for free if you bring it to them.

Locate the dipstick tube to check the trans oil and remove the dip stick and put the oil down the tube. Replace the dip stick and check the level when you think you have enough in the tranny. Hope this helps.

93 chevy g20 have speedometer cable


The speedometer cable should not have anything to do with changing the ball joint. it goes directly to the transmission on a 93. your grinding sounds like either someone didn't get the bearing back in the hub right or loose bolts on the wheel ..

Auto trans wont change gears speedometer jumps up and down


Have you checked the fluid level? if not do so with engine running in park and e brake pulled Also look at the fluid is it brown in color and smell sort of like onions? if it does it needs a filter and oil change. most cars require the filter and oil to be changed every 30,000 miles. Also add Lucas transmission additive so that it will soften the seals and clutches. If you want to do this yourself let me know and I can give you instructions, however it can be messy. the transmission will take 12 quarts of fluid dexron III and the lucas oil conditioner. Write back if you need more help and thanks for using fix ya.

'93 corolla,4 spd.auto trans.speedometer reads10 mph slow and the transmission shifts real fast.Its in third gear bythe time u hit 30 mph. Also wont downshift at this point either.


well what you want to do is change the trans control solenoid or the trans modulator.i know this car has a trans modulator but im not sure that it has a trans solenoid.either way it's a lot cheaper than changing the trans.hope this info helps. take care and good luck, manny

My van has 6 cyl. trans is auto. and electonic, and my problem is it want change gears. you can change them with shifter, but it want on its own I was told it has electronic cylnioids to shift trans, could...


Sixteen year-old van...a vehicle this age with the problem you describe likely needs the fluid and filter changed at the very least. If this doesn't fix it, unfortunately, you are going to need more extensive work, possibly even an overhaul (this is what I suspect). The solenoids get the signal to engage from the ECM. It is unlikely that the solenoids are bad, because they engage the shift valves whether used manually or electronically.
Good luck.

I have a 93 Chevy Suburban 1500 and the Transmission won't shift into any gear. I have an 1983 Chevy Suburban Transmission that is still good. Can I use the 83 Transmission in my 93 Suburban?


Not without a little adapting. The 1993 has a 4l60e which is electronically controlled and has shift solenoids. If the 83 is an overdrive it is a 700r4 which is the same trans but not electronic. If you put it in the speedo wont work and you will need to install a T.V. cable so the transmission will shift. The 93 won't go forward or backwards?
