Try changing you transmition fluid and its filter first , if this doesn't in prove your bands in auto trans may need servicing or you may have faulty gear solenoids .you fluid should get higher as gets hotter this is normal , always check fluid after driving , do not over fill this is just as bad as underfull.

SOURCE: 97 gmc pickup with automatic transmission trouble

1st thing to do is test the system for codes, the problem is most likely a failed or stuck shift solenoid indside the trans, have you ever serviced the trans, sometimes a fluid and filter cahnge will cure these kinds of issues.

unfortunately if it is brown rusty color you have a serious problem! this usually occurs once you have burned up the clutch plates with in the core of transmission! honestly I do not aim to discourage you but your probably going to have to eventually change this transmission! if you have a strong aroma from the dip stick it is burned up!!!! I have change plenty of these over the years due to the same circumstances.Good luck and hope that it all works out for you,John

SOURCE: Power steering fluid leaking

It all depends on where the fluid is coming from. It could be a ruptured pressure hose, or a seal in the power steering pump. The 2 "dangers " are NO POWER STEERING and burning out the pump with no fluid. A short drive for repairs using " ARMSTRONG " will probably do no harm. Hope this helps

Why is the transmission slipping when first started?


Sounds like dirty fluid and filter in the transmission. A filter and fluid change might help a great deal. The quicker the better

Transmission not shiftin



For car not changing gears it can be shifter assembly issue, or it can also be transmission issue. Get the shifter assembly inspected with ignition OFF.

It sounds like your transmission is slipping. Have you checked your transmission fluid level? That would be the first place I would start looking. I hope this helps you out and if you have any other questions please feel free to ask.

It is like the transmission is slipping for the first few minutes till it warms up


That is very often a sign of low fluid.
Sometimes it isn't really that it's cold, it's that after a vehicle has been sitting for a little while the fluid drains back to the bottom, to the pan, so at start up it runs fine because the fluid level is high enough for the pump to function properly, but, after a few minutes of running the level in the pan drops too low for the pump to function properly.

If you know your transmission fluid level is good, you may consider having the, "shift solenoid" checked.

I hope this helps you.

Ihave a 1997 mazda protege and after having it for a week I noticed the transmission will slip when going into 3rd gear (automatic transsion) the fuid is brown and I was worried about really messing things...


.One of the most common causes of a slipping transmission is a low automatic transmission fluid level, also a dirty and/or clogged automatic transmission filter can impede the normal flow of automatic transmission fluid throughout an automatic transmission and cause the transmission to slip. Adequate, unobstructed transmission fluid flow is necessary for the optimal operation and function of an automatic transmission, including the function of the transmission bands and gears, two transmission components that routinely cause transmission slippage.Another cause would be faulty torque converter action and maladjusted transmission band.
