I just bought a t5 swap kit for my 85 iroc and just realized that the t5 has a electric vss but my car has a mechanical speedo cable. How do I fix this issue without buying a new speedo?

 

A. Remove electric sending unit from new trans.

B. Remove cable gear holder "bullet" from old trans.

C. Place Part B into Assembly A.

 

Even though the old trans is auto this will work?

What year tranny? I need a vss from a 91-92. My current t-5 is from a 84 or 85. Maybe we could trade parts?

 

how the hell did you find a elctric speedo t5? lol dam like the guy above said try and trade parts...if you cant trade him let me now.

 

LOL right! My speedometer is an aftermarket tach......

 

There is an electronic speedometer sending unit on eBay for a T5 right now type in 25007350 that's the part number

 

I have a spare t5 mechanical unit if needed

 

Do you still have this part available? I have a WC T5 so it has the electronic speedo plug and my car has the mechanical cable

 

https://transmissioncenter.net/produ...-gears/page/5/ The Turbo 350 stuff is also for T-5.

 

Incidentally, you can probably sell that electronic one for MUCHO $$$$$. They're not very common, and demand is MUCH higher than supply.

 

There is a range of TH350 Chevy stuff with the same bullet diameter as the T5, but the gears are different.
Third gen T5 had smaller diameter driven gear, with 22 tooth max, and a large dia. drive gear.
TH350 stuff had larger dia. driven gear, max of 24 or 25 tooth, and a smaller dia. drive gear.

If you get matched gears, cool. If you try to use a T5 gear with a tH350 gear, nope.
