hay you have a lt1. look here, its to adjust tps, the same way can be used to see what volts its putting out at wot. https://camaroforums.com/forum/93-02...-sensor-70605/

 

Got the TPS checked. Idle is .65 and WOT is 4.65 on the blue wire. The black wire read .03. Thoughts?

 

lmao this book,,, it says about 5 volts is wot. im thinking 4.65 is low. not so sure on the .03 but i think thats ok, its the ground. try unpluging the etc (temp sensor on the water pump) and see if the .03 changes. in my 93 book it shows they both get there ground from this wire. blue is tps sensor signal and the gray is the 5 volt reference input. as you moved the thottle did the numbers change smooth or jump.

 

I got you. And as I moved the throttle the numbers were smooth and gradually went up..

 

really need to see what trouble codes you have stored. have the car scanned for trouble codes, may have to go to trans shop fro trans codes. hay could for piece of mind, check your grounds. computer ground is on the block in front of the starter, ignition ground is below the ignition coil module, also check that ground strap under that, check/clean the wires on the ground junction on the passenger side fenderwell, have a look in the power juction box as well, red plastic box nest to ground junction. while your under the car check the wires and plug connections to the trans on both sides. look along the exhaust for any wires up against it or by it that look burned.

 

Cool. Thanks for all the help. I'll fill you in when I can get the code checked.

 

I have a 94 z28 and it drove fine until I got home. when I went to back up it started making a grinding/rattling and would not back up or go forward unless I got the rpms up above 3500 and it barely would move. does that sound like the tranny is gone. please help

 

well if it wasn't it is now, have you checked the fluid level yet?

 

Check the fluid, scan for codes, and then drop the pan and inspect for metal. Sounds like a planetary may have broke or something.

 

I found a tranny from a 96 caprice its the same length but that's probley about itwill it work in my 94 z28
