Is there any way without going full manual or adding a shift kit to bypass the computer controlling shifts? I would like to be able to make it shift because right now when I am on it it will not shift correctly and usually results in bouncing off rev limiter and I fear the problem may take the lives of the valvetrain components.

If anyone knows any way to do it please let me know.

thats a really good sign the trans is on its way out and you may want to start thinkin about a rebuild rather than a way to controll shifts

I am going to rebuild it SOON but I was thinking until then. Oh well I guess it will be sooner than planned

Well, if you have to pull the transmission, put a TH350 in the car. That solved my PCM shifting problems!

yeah that will also solve that silly problem of the car shifting into 4th and saving you gas

With the mods I have...........I quit caring about fuel mileage LONNNNNG ago!

Don't they make skip shift eliminator for automatics? That should work right?

Well you could build some sort of shift box and plug it directly into the trans we have one I built for testing purposes, Basically its three toggel switches two control the shift solenoids and 1 for the tcc. Ours also have a presure control but if you were only using it for wot racing then it wouldnt be needed. Just and Idea ,

My trans only has a couple thousands miles and seems to do the same thing that the OP stated. I think it's in the tuning. Is the OP's car relatively stock?

If the trans is in good shape then likley its a matter of tuning , Particulary with mods to the engine the RPM rises faster but the time it takes the trans to shift from one gear to another is a constant. So depending on when you have it set to shift there may not be time to complete the shift before it hits the limiter
