PineClone Posted August 7, 2013 Report Share Posted August 7, 2013 I am enjoying my new 5 speed A LOT! Noticed that the speedo is off, as well as the odometer. I put 14" wheels on prior to the swap, but i didn't notice any significant difference in the speedo/odo reading after that. However, after the tranny swap i notice the speedometer reads about 5 mph fast. I used the speedo cable from my automatic tranny. I notice on RockAuto they have cables for the auto and for the 4-speed. No 5-speed listed, but my assumption is that the 4-speed would work. Wanted to verify here...will the cable actually make a difference?? Thanks. Quote Link to comment
Eagle_Adam Posted August 7, 2013 Report Share Posted August 7, 2013 the cable wont matter, its only a length difference. There is a speedo gear you need to change Quote Link to comment
datsunaholic Posted August 7, 2013 Report Share Posted August 7, 2013 The difference is because the vehicle the 5-speed came from and the car you have now had different rear gear ratios. The speedo drive cog reads output shaft speed of the transmission, so that has to be changed. Quote Link to comment
PineClone Posted August 7, 2013 Author Report Share Posted August 7, 2013 Need to take out the dash to get to the speedo to do this? Quote Link to comment
Eagle_Adam Posted August 7, 2013 Report Share Posted August 7, 2013 No, it's a gear in the trans Quote Link to comment
j_boy_619 Posted August 7, 2013 Report Share Posted August 7, 2013 Yeah mine is off by about 10%. If the speedo reads 60, I'm probably going 54-55 ish (EDITTED) OOOOPS Quote Link to comment
PineClone Posted August 7, 2013 Author Report Share Posted August 7, 2013 Yeah mine is off by about 10%. If the speedo reads 60, I'm probably going 64-65 ish Hmmm. If my speedo reads 60 i'm probably going about 55-56. My odometer is reading short...Or in other words, it reaches one mile about 150 - 200 feet before the mile marker. Quote Link to comment
Dguy210 Posted August 7, 2013 Report Share Posted August 7, 2013 Yeah mine is off by about 10%. If the speedo reads 60, I'm probably going 64-65 ish MIne is the same way. I calibrated it with a GPS and it is almost exactly 10% off, but I run big tires on it so this is not unexpected. Quote Link to comment
CWhip Posted August 7, 2013 Report Share Posted August 7, 2013 This is what it looks like pulled out. You can get one with fewer/more teeth to correct the speedo. 1 Quote Link to comment
PineClone Posted August 7, 2013 Author Report Share Posted August 7, 2013 Dumb question...will the one for the automatic work in the manual? Figured i'd ask since the auto is sitting in my garage being useless at present. BTW - anyone need an automatic?? Quote Link to comment
datzenmike Posted August 8, 2013 Report Share Posted August 8, 2013 Pretty sure auto and standard pinions are not the same. Exactly what 5 speed did you get> 60 series or 63A series? You'll have to pull the one you have out and count the teeth or get the color of the plastic cog. To slow the speedometer cable down you will need a cog with more teeth on it. 1 Quote Link to comment
CWhip Posted August 8, 2013 Report Share Posted August 8, 2013 I'm not sure if the housing will swap but you should be able to drive the retaining pin out and swap the gears. Btw, you will lose fluid if you pull them out. If you jack the rear end up far enough it should be minimal. 2 Quote Link to comment

CWhip Posted August 9, 2013 Report Share Posted August 9, 2013 I'm not afraid to admit it when I'm wrong. That being said, I am wrong. Sorry guys! Quote Link to comment
datzenmike Posted August 9, 2013 Report Share Posted August 9, 2013 Well I'm saying I don't know for sure. Part numbers are no where near the same, my gut says no. Quote Link to comment
CWhip Posted August 9, 2013 Report Share Posted August 9, 2013 Prove of my wrongness! The red gear is out of my old auto and the green is out my manual. Big difference! Quote Link to comment
PineClone Posted August 9, 2013 Author Report Share Posted August 9, 2013 Well that will save me some time. Hmmm. :confused: Quote Link to comment
CWhip Posted August 9, 2013 Report Share Posted August 9, 2013 Yeah sorry! I'll go back to quietly lurking. Quote Link to comment
PineClone Posted August 9, 2013 Author Report Share Posted August 9, 2013 Yeah sorry! I'll go back to quietly lurking. Nah...appreciate the help. I hadn't started working on this one yet. Quote Link to comment
datzenmike Posted August 10, 2013 Report Share Posted August 10, 2013 Yeah sorry! I'll go back to quietly lurking. . Speak up any time you have an idea or opinion. Even if wrong info gets shuffled around and someone learns something, maybe some kid in ten years will read this. 2 Quote Link to comment
