Automatic tranny troubles, car wont shift gears?

[StreetDreamsGT]

This post may look a little familiar but I figured I had to repost it to clear up that I have an automatic transmission not a manual. I recently had my car put in a shop to have my exhaust taken care of and my new motor mounts (ENERGY SUSPENSION!!!!!) tossed in. Drove it home, and I noticed the rpms kept climbing well past normal. Normally they'd switch up tween 2500 n 3000 or so I hit 40 n was in 4000 then I pull my foot off n the car pretty much stayed there I stepped on it again and the car revved till it was back at bout 4000 n then i felt it kick in. For the whole time I've owned my car it's shifted round 2500/3000. Today I pulled the filtler and changed the fluid, there was a small metal piece in the bottom of the pan, looked like the dipstick kinda, a lil thicker n bout an inch long. Anybody know what could be up?

How's the throttle valve cable bushing look on the throttle body?

don't think it's in bad shape, i'll have to take a closer look @ it tomorrow, what kinda effect could that have on it?

A bad cable or misadjusted one can cause the problems you are having. Take it somewhere to get checked out since a badly adjusted TV cable will fry a transmission easily.

sounds like tv cable changed during motor mount swap.

If the piece looked like a little bouy, then that is the factory plug that goes into the dipstick tube apeture to keep crap from falling in. Toss it. You said you pulled the pan. Is the fluid level fine and the fluid look ok?

If the fluid is low, it will ...lose gear and neutral.... at lights and such and when you rev it and the pump turns, it will suddenly jump into gear and the car will move.

If it's revving past it's normal point and doesnt shift either

1. If it feels like it's neutralling above the normal rpm shift point, you have a stuck valve in the valvebody. Remove valvebody and move everything around till you find the culprit, remove valve and turn in steel wool, reinstert and repeat until it's moving freely

2. If you're powering above the shiftpoint, the TV cable needs to be lengthened since the trans thinks you are at full throttle.

Get under the car at drivers side, about halfway down and feel up where the shifter cable goes in. There will be a second lever there. Make sure it's free moving. There is some way to adjust the clip on the throttle lever below the TB by pushing the clip out but this method never works properly. You want the cable just tuaght when the throttle is closed and fully pulled with the throttle wide open. The factory system is calibrated for factory geometry so I agree the motor mounts are the cause (unless the lever is stuck). Lowering the motor also lowers the trans, remember that.

Here is the standard adjustment method:
