i have a 93 camaro z with 2.73 and I changed my gears to 3.23 which sensor for my tranny do i need? I need for someone to read their p/n off of a 3.23 car basically cause the dealer's around here seems to not know what i'm talking about and can't order the part. 4L60 is non electronic. thanks

 

I think the 93 still used gears on the VSS to adjust for tire size/gear ratio?

 

You have to change the "drive" and "driven" gears in the tranny. Sorry, I don't have a part # for your setup though. You could probably call a dealership and ask for a part number on them.

 

cant really help you out w/ that one but check out the speeddensity.org(something like that). they can help you out its a 93 specific forum. ive been there a few times and they helped me out a lot.

 

the dealer's out here are dumb *****, they can't tell me which sensor is for the 3.23 car cause they don't know
i'm going to e-mail detroit to get to the bottom of this.

 

Like said before, you need to change the gears, no sensor.

 

You need to change the speedometer gears. There is no sensor that you can reprogram. Try contacting Lingenfelter, they offer recalibration gears for most rear end ratios.

 

What's this talk of gears? My 93 has electronic sensor speedo for the tranny, no cable.

Pretty sure anyway


Edit: I just crawled under my car with a flashlight (yes at 2am here) and I did not see any #'s on my sensor. BUT, I guess it does look like it could be a gear driven sensor

 

93 4L60 has a drive and driven gear behind the speed sensor, 94 and up has a electronic speed sensor with two magnetic strips on it.

 

better yet does anyone have the option code for 3.23 gears in the 93 z28. D8A, D8B, D8M, D8I or D8N?

 

Thanks guys, but I found it.
The part number is
10456089 for the 3.23 car/ D8I
10456088 for the 2.73 car/ D8?

 

if you still didn't order them and if they are expensive let me know becuase I have a couple left over from the A4-M6 conversion that I will just mail to you. Just email me at z1bad93z@hotmail.com

 

I found them at www.acdelco.com the easy way to tell 2.73 is black and the 3.23 is white
