Hi guys, I have the WC T5 behind my 327 now. Everything is great except now my speedo is off -- I had it perfectly calibrated with the muncie 4 spd, but the muncie's speedo drive gear (on the output shaft) did not fit the WC T5 output shaft so I had to keep the stock gear in the T5. With a 19 tooth driven gear the speedo reads way too fast -- I grabbed a 22 tooth driven gear at the junkyard today and I'll see how that does. However I'd like to calculate what driven gear I actually need -- what drive gear will this 1989 Camaro 305 tbi WC T5 have in it?

 

that is a good question I am also trying to figure out that same question.


Anyone out there know?

 

Either a 7 tooth or a 9 tooth.

try bottom of page for speedo calibration

 

just because that program says what should be in there doesn't mean that is what gm used. I'm not going to go out and buy a driven gear if I don't know for sure it's the right one.

 

Their selection of gears for the 700-R is just flat out wrong for the given combinations against what GM used in cars with a 26" tire.

 

not to mention we're both using t-5's

 

The calculator is wrong for T-5 combinations too.

I gave up on "online gear calculators" a long time ago so I didn't bother reading the whole page. All the calculators are wrong, thus far.

 

TBI's with 5-speeds all had 3.08 gears as far as I know, which is a 9 tooth red drive gear and a 22 (or 23 tooth) driven gear. Sorry I cant remember if its 22 or 23 nor what color the driven gear is...
