ok i have a H22a swap in my EG and I'm trying to figure out what transmission i have so i can rebuild it, but the sticker with the bar code and number on it has been removed. is there any other way to tell what tranny i have, or is that stupid sticker the only way?

 

Gearing...at such rpm what are the speeds in 1-3 gear

 

at 3k rpm 1st is around 15mph 2nd 30 and 3rd 45 but my speedo isnt 100% accurate so that's probably not exact

 

Crack n Count! Only way to be 100%

 

Count what? I know very little about transmissions.

 

Not practical if he's driving around on it without issue.

Op, what size tires?

Then break out the gps and write down rpm vs mph for different gears.

3k and 5k plots should do it.

Then you can crunch numbers and you'll know within reason.

Final drive can be extrapolated from gears calc'd based on rpm drop from a 5k shift in each gear.

 

My speedo is only off by like 2-5 mph cuz my tires are 45 instead of 50. But i still dont get how im suppose to tell what tranny i have by my speed. Can you please explain? Like i said im kinda dumb when it comes to transmissions i have never worked with them.

 

Some transmissions have shorter gears and some have longer gears. By knowing which rpm's your pushing at certain speeds we can narrow down your transmission by gears. Look for the stamp above the passenger axle and give us that number also

 

yeah my speed at 3k is 15 in 1st 30 in 2nd and like 43 in 3rd. if you guys need more i can get it but there was to much traffic today to get a 5k reading. and its like -15 right now so i don't really want to be out there looking for a stamp unless i absolutely have to.i can get it this weekend when it warms up a bit. is the stamp on the bottom side of the tranny? because i couldn't find anything on the top side.

 

What size tires do you have? 195/50/15?

 

True...but the OP said he is going to rebuild it
Plainly stated in the first post that he wants to figure our what he has so he can rebuild...if it's going to be cracked open for a rebuild...why base the replacement parts/gears/Final drive off of a close guesstimate of MPH to RPM.

 

no my tires are 205/45/16 and i got 5k readings today as well its 25 mph in 1st, 45 in 2nd, and 67 in 3rd. still no stamp its way to cold out ill work on the in a couple days when it gets a little warmer.

 

I'm gonna rebuild it eventually but i just want to figure out what tranny i have so i can start pricing stuff out/ordering what i need a little at a time. i just don't understand why they put a stupid sticker on it that easily comes off instead of just stamping that **** on there. it would make like a little easier.

 

Last question op:

What rpm are you at in 5th gear at 55mph / 65mph / 75mph?

 

5th gear at 55 in 2200 65 is 2500 75 is 3000
