I'd definitely have to say this is a problem, but it may have a bright side to it in some way. I was playing with the throttle cable, as said in another thread, and when I went out to test drive it it seemed to drive harder and faster than before. So when I got home from work I decided to see what exactly it did differently.. and it kind of shocked me.

This is the Throttle TV cable adjuster, correct?



Anyway, I slide it all the way back as instructed, and went WOT to reset it and so on. So afterwards I test it out and it seems like it hauls a lot harder now, which seemed awesome at first.

Then I get home from work, eager to take my newfound joy out for another spin to see why it's acting like it was.. and found out in the first 100 feet. The throttle is slightly more responsive, but the RPMs it takes to shift drastically increased. It takes roughly 1k more RPMs per gear to shift, but I'm also going faster yet giving it the same amount of throttle as before. An example may help:

Pedal 1/8 to the floor from stop - Before: Would shift into 2nd at ~16mph @ 1400 RPMs. After: Shifts hard(actually throws me back in the seat a little) around 25mph @ 2500 RPMs. Third gear hits around 34-38mph depending how fast the cruise is, and overdrive is at a whopping 60 when it was only around 42 before. Can anyone explain this? My RPM requirements for shift almost doubled because I tweaked the cable, and I tried putting it back to the original position to no avail.

I guess what I'm asking is, is this normal? What do the rest of you auto guys run for RPMs and speed at shifts in your 86s? I can definitely see a plus to this.. but did I mess up my tranny? I sure as hell hope not.

 

Can't say for sure because my LT1 is different but I believe you adjusted the TV cable, not the throttle cable. It is critical the TV cable be adjusted according to the FSM or trans damage can occur. Do a search to see if PeteK posted the adjustment method for your engine, I know how to do it on the LT1 but it is entirely different due to the ASR.
In the mean time don't drive it to prevent any further damage, good luck.

 

John A. Marker posted it as a response to Demonic86's query of throttle response. The adjustment seemed simple enough, and I followed everything he said. I've heard of others doing it too and figured what's the worst that could happen - apparently this.

 

I'm not saying that the post was incorrect, I don't know. I do know that you must be critical of everything posted on-line, much of it is wrong.
That is why using the FSM is recommended by so many, it isn't perfect but your chances are much better that a given procedure applies to your particular vehicle, there are many variations between early and late cars.
I wouldn't panic yet, the rrans may shift fine once the TV cable is properly adjusted.

 

I usually post this link when this comes up. Not sure if you have seen it but it may help.

If you followed the directions, and it sounds like you did. That is the correct adjustment per the FCM. The adjustment is a no brainer and difficult to screw up if that is possible.

Sounds like there may be other issues with the trans. Our trans expert PeteK may know.

 

All you have to do is push the tab in. Then push the cable in all the way and release the tab.

There should be no slack in the cable. I was taught this method by a tranny expert. It's also the method in the link above psted by Agent 86. Either method should work if done properly.

 

My trans never had issues before this happened. It would always shift reliably and at the same RPMs time after time.

I pushed the tab in, pushed the slider all the way back, let go of the tab, and then hit the pedal to the floor to re-adjust it. The car was on while I did that, is it okay to try while it's off or does it have to be on? It was also a fast punch and not holding it to the floor for very long.

The link Agent86 posted said that my trans may be working in high pressure mode. That sounds about like it to me. Could you guys go into a detailed description on how to adjust it?

Edit: Okay, it's fixed. I wasn't pushing the pedal hard enough to the floor. I re-adjusted it today and stood on the pedal, hearing a few clicks and apparently that reset the TV cable where it had to go. I still notice a few higher RPMs and 2nd gear hits more than I remember, but that might've been the lack of throttle I was missing.

 

instead of pushing in the pedal, you may want to go WOT by moving the linkage on the Throttle Body

 

excellent idea-that way you can also check if the throttle baldes are opening all the way- on my 95 they weren't,and after the adjustment,d the difference in overall driveability was incredible amd phenominal at the same time-top that

 

Mine under light acceleration shifts 1-2 at 18MPH, 2-3 at 31-33MPH. My tranny guy set mine up to go to OD at 55-60.
