Offroad Trailblazers and Envoys

Change trans fluid and filter or not?

Something not working right?

by Blazintrails03 » Fri Jun 14, 2013 10:35 am

So I'm at 96000 miles and having a slight slip in low acceleration. If I pull from a stop sign in a 25MPH zone it will slip a little in what feels like all gears. But if I merge onto a highway and get on it to speed up with traffic I don't feel it. Would you guys recommend dropping the pan and changing the filter and maybe later the transgo shift kit or leave it alone and not touch anything. I don't have the money for a rebuild right now.

Pan drop and change filter, is what I'd do.

Im gonna go forward with the drain, fill, and filter change next weekend probably.The dorman pan is nice but I'm on the fence for now. As an unneeded expense and plus the fact that I don't know if ill have the tb the next time the Trans fluid needs to be changed I'm not too worried about it.

A bit late on this one, but a cheaper option for anyone that wants a drain plug is a bolt-on drain plug bung. Drill a hole in the pan, install bung, reinstall pan... voila, you have a drain plug.

I looked into the bolt on option but seems like it was around $20 and the Dorman pan was something like $35. Knowing my luck with the drill I would booger up the OEM pan and have to buy a new one anyway :-)

I've been slacking on this and my air bag light between the weather lately and my job. I've decided that I'm gonna go ahead and pick up the larger pan though.

While you're up in there, it would probably be a good idea to change out the pressure control solenoid. Slippage at low throttle but not at high throttle could be that the solenoid has collected so much "magnetic mud" that the output pressure at high current (low engine torque) is lower than it should be. Feel free to ask me how I know.

Anyway, they are cheap enough, available from your local trans shop or Transtar dealer or off the internet, and easy to swap out.

Matt at this point I'm kicking myself because a number of people mentioned this to me and I didn't do it. Probably gonna go back in there and replace the solenoid some time soon. I've seen stuff through searches where there is 1 and 2 of these how many are there? Is this what I am looking for?

Anything else I should consider while I have the pan off again :facepalm: ?

There's two solenoids of that style in the side of the valve body.
