My tranny's shift points are all screwed up!

[d0n_3d]

Ever since I have been messing around with the T.V. cable I haven't ever got the tranny to shift right...I tried the GM recommended setting numerous times and I still have problems. 1-2 shift is ok...pretty firm at cruise and shifts at 13 mph...the 2-3 is horrible...it keeps "flaring" no matter where i set the cable...right before it shifts from 2-3 the rpms jump up really fast like 200-400 rpms depending how much throttle i am giving it and then it shifts very slow into 3rd...this happens at around 23 mph...the 3-4 shift is ok as it shifts around 35 mph...

now at WOT it shifts awesome...shifts firm right at 5200 rpms in all gears...my main problem is just that flaring of the 2-3 shift...it just feels like it's constantly slipping gears when at that speed...only happens at normal cruise! my tranny is bone stock with nothing done to it, 92k miles roughly...

question about adjusting that tv cable...say i put it at the factory setting...now if i pull the cable a little more towards the firewall is that delaying shifts? if i pull the cable towards the radiator more is that making the shifts slower? i don't understand how that works...does it need to be tighter or looser in my situation after i set it factory?

i just reset the tv cable again...pulled the cable all the way towards the firewall...then went inside the car and went complete WOT with the pedal...it clicked a couple times..

now on the back of the cable housing (closest to the firewall) there's a bunch of rivets showing...i counted 6 indents showing exactly...is this the correct location??? i am STILL getting that 2-3 flare up...every gear is fine while cruising except the 2-3...now when i go about 1/2 throttle the rpms jump way up like it's downshifting into a lower gear it isn't supposed to...this tranny is all messed up...sigh i am about ready to just take it to a tranny shop and let them fix it...i can't seem to get the shifts correct

Your 92k-mile transmission is showing classic signs of getting tired. Someone familiar with 200-4Rs may be able to check and readjust your band clearance and eke some more life out of it but chances are the direct clutches are wearing too and the inevitable overhaul is looming.

i plan on having this thing rebuilt over the winter during storage months...but i want it to last a few more months...the thing that gets me is it shifts firm and awesome at WOT...shifts right at 5000-5200 rpms with no let up...it's just cruising around with that 2-3 shift flare is the only problem...and it just started after i began messing around with the tv cable! should have left it alone
