what can i expect from this VSS if i change it (however im supposed to do it) i swapped my stock 3.08 to a posi 3.45 and searched around on here only to find out that i need to tweak it..does it affect rps and mph? anyone with any knowledge please feel free to hit me up with some info on this ive tried to find out on my own but with no luck....thanks all.

 

you don't have to change the vss, just the drive gear. Check the sticky in this board called "t-5 drive/driven gears" to find out which you need for your application.

 

I had my rear end swaped about a year ago, havent got around to chnging the driven gear, but this site is where you can buy them, a quick search will tell you more.

If your have 3.45" in your rear like me, you wwill actually need the drive/driven gear for a 3.42 as they dont make drive/driven gears for 3.45"s.(as i have been told) the end difference however, in the amount your speedometer will be off, is only like 1-2mph, recently though in the thread i got that link from, it said that you need a blue 7 tooth drive gear if you have 3.23 and up and for 3.45 you need a 20 tooth driven gear, the site has both for sale, so obviously i have some conflicting info, maybe someone who is more of an expert can speak up and clear that up.

 

so you mean to tell me that i have to go through all this cursing, sweating, frustration, and anger to change a VSS cable thing just so my speedo wont be off 1-2 MPH? LOL. your crazy, if thats really all there is of a change i say screw it and leave it alone. unless theres more to it. anyone??

 

no no no, lol if your going from something as low as you are your speedo will be like 10-15 mph off, when you switch in the 3.42 drive driven gear set, it will be 1-2mph of from what it really is(since you will have 3.45 gears and not 3.42). But as i said i have conflicting research now, in the fact that they do make 3.45 drive/driven gears. If that is the case than your set and by switching them in you will be right where you want to be.

i went from 2.73 to 3.45 and my speedo is off by about 20 something.

 

ohhh that might be all that vibrating when im going "90" so your saying when it says that im really going like 110?? just to know so i have a clue when im actually driving i have an idea of the REAL speedo lol. well if thats the case ill swap it out. did you do yours already? maaannn thanks for that info i appreciate it bro.

 

uuuuuuggghhhhhhhh
no its more like ur going 70.

when i put in my 3.73 the speedo read like 65 when i was going like 25, so yeah change out that driven gear to get an accurate reading

 

well keep in mind that i have 3.45 gears and not 3.73 and i think saber covered all that info already

im confused your saying either 7 tooth or a 20 tooth? im gonna get some info and figure it out, hope that $hit aint expensive.
hey to anyone thats done it already, is it a real pain or what? im tryin to figure what thing thing looks like if its just that wire that runs from the guage to the trans or w/e
me and a friend changed a cable in his el co for his MPH so im wondering if its something like that also. thanks all.

 

No need to waste your time wondering. You have an electric speedo, your friends El Camino had a mechanical speedo. Check the sticky about drive and driven gears, pick the closest application for you (3.42), and put them in. Nothing to do with wires running to your speedo or any of that.
