hey people, i'm about to do the 700-R4-T-5 swap in my 91 Z28
the T-5 tranny is coming out a 85 TA. As far as I know the speedo setup in my 91Z28 is a vehicle speed sensor/electrical setup, and the one that the t-5 uses is mechanical

Whats the best way to get my current electonic speedo to work with the mechanical one from the 85 TA T-5?? please help as i'm clueless about this stuff.

 

Put a mechanical speedo gear housing and gear in the T-5.

Total no-brainer.

 

I think you worded your post wrong.

Your 91 Z28 uses an electrical connector for the speedo. The 85 T5 uses a mechanical speedo. You need the speedo setup off a T5 with the electric speedo......

When are you doing your swap? I'm swapping a '92 T5 into my 85 IROC and I have to remove the 92's electrical setup for a mechanical speedo housing and gear anyway, so if you want, we could swap.


Email if interested.


HTH

 

will the electric speedo setup from a 91 Z28 T-5 plug right into the T-5 from the 85 TA Donor car?

 

yes

 

so all i need is the speedo sensor from a 91Z28 T-5 to plug into the 85 Trans Am T-5?

 

yes

and of course the correct gear to go with your rear end gears and all that, just like any other speedo situation.

FYI, I went the other way.... 91 trans into 83 car.... direct bolt-in. One 10mm head bolt.

 

hello, i just bought a 1991 z28, and the speedometer jumps around...well, i think i might have figured out why. got the numbers off the trans, and its off a 1992 truck ...diff speed sensor than the cars 4l60 trans. anyway, how hard is it to change to the correct speed sensor? any help would be great. thanks, tom
