84 vette auto trans problems
Did a smog pump delete on my 84 c4, runs fine but tranny shifts at high points now between 1800 and 2000 rpms. Like a high stall converter was installed, any suggestions thanks.

The link that CROWS gave is for the Tune Port, but the procedure are very much the same for the Cross Fire. you just need to go a extra step, you have to remove your air cleaner housing and get down to the Throttle linkage bridge.
when removing the Air cleaner housing take lots of care to disconnect all the Vacuum lines CAREFULLY, and it would not be a bad idea to have some extra Vac. hoses on hand by now if the hard plastic lines have not broken and not been replaced it could be an Aggravation not a big problem but a Aggravation.
If the cable adjustment doesn't fix your problem, you may need to look at a sticky Governor in the transmission. which would be a whole other chapter for another post.

when the throttle is closed the cable should be under lite tension, you should be able to pull the cable and it should move freely. But under WOT the cable hits a tension point/stop inside the trans and something has to give that's when the adjuster will ratchet. So yes it should be fairly tight.
I have in the past have given the cable a extra click or 2 but usally no more to soften the shifts for customer's who did not like a jarring shift.
