Full throttle, won't shift into 2nd????
 

When under full throttle at the 1/4 mile she wouldn't shift into second gear. She would just keep jumping off her redline and not shift. Has anyone else experienced this, and what is the problem??

Unplug your battery for 30 mins and see if that fixes it...sounds like the pcm could be off...possibly even the tranny is going bad on you...but being a 95 model it is electronically controlled so I'd start with resetting the pcm.

It also sounds like a computer issue. Have you ever had your PCM re-tuned? Either that or you transmission doesn't have enough pressure in the lines to shift into 2nd.

The PCM uses the TPS and vehicle speed to determine shift points, another direction to look.

What should the TPS be set at on a '95? I know on my '88 GTA it is at .54 volts, what is it for a '95 LT1??

And no I haven't had the pcm retuned. I was thinking of getting the HPP III because I will be installing a set of 3:42's and wanted to adjust the pcm for that. Also wanted to lower my fan temp. And now I could try to adjust my shift points and firm them up, maybe that could work?

I had the same problem
 

My car is off the road now because my tranny is shot. I started out with the same problem that you described. I found out the my car had problems when a piece of crap civic decided to race me. I raced him and then when I was expecting my car to shift from first to second, It didn't.

I waited it out and it got worse over time. Now my car is off the road until next year because I am not putting it on the road for 2 months and then taking it off for winter.

My tranny is shot. I forgot to say my car is a 95z28. Your problem may be computer, but the important thing is to check that tranny fluid. If it smells burned and is black or brown, your tranny is shot. There is nothing you can do other than fix it or let it get worse.

When closed it can be between .4-.7 volts. When fully open it should be about 4 volts more than when closed. My thinking was if it's not showing 4.X volts when fully open the PCM will not tell the tranny to shift.

Good call on the tranny fluid...granted my experience with the 700R4 are all before the electronic version was available in the F body but tranny fluid is critical in an auto trans and makes a huge difference in these transmissions in the way they shift, and when/where they shift...
