is this possible? do i just need the second gear gear?

EDIT : i am doing all the labour myself, i have also got a 4.785 FD and ITR LSD that i am swaping in, so please just need an answer abt 2nd gear...

IF YOU DONT KNOW, DONT POST....

for the time, money, work and effort you could buy a new tranny

edit: besides you will have a HUGE drop in rpm's from second to third, about a 36 mph difference between the redline in both

 

a second gear costs as much as a new transmission?

am i in "bizzaro land"?

 

why would you just do 2nd gear? lol i don't get it? and a second gear doesn't cost as much as a new tranny, but the labor will

 

hey buddy, if you *could* just answer the question instead of hating, i would be appreciative,

but since you see fit to question my ratios, here is a better chart for you to criticise...


Tire Diameter 23.07
Final Gear 4.785 RPM(shiftpoint) MPH KPH RPM Drop
1st Gear Ratio 3.230 8,000 35.53 57.17
2nd Gear Ratio 2.105 8,000 54.51 87.73 5,214
3rd Gear Ratio 1.360 8,000 84.38 135.79 5,169
4th Gear Ratio 1.034 8,000 110.98 178.60 6,082
5th Gear Ratio 0.787 8,000 145.81 234.66 6,089

 

All gears are interchangeable between the 2 boxes. I put an ITR 3rd in my GSR and am glad I did it. I just wish I had changed out the 4th gear too.

Don't get too bent out of shape on the cricticism. I'm sure by now you've noticed that in H-T land, everyone knows more than everyone else. It's a bit of a conundrum.

no, your cost after everything is said and done to buy and install it

k. thanks man, i know that all the gears are interchangable, but just need to know if i only have to buy one thing - the 2nd gear it self?

did you have to swap 3rd gear + 3rd counter gear?

 

Yes you have to change the gears as a set. That's what gives you the specified gear ratio.

 

so since there is only one 2nd gear, that is all i will need, right?

 

You need the second gear and the 2nd gear counter gear.

that is my problem, as far as i can tell, there is only one 2nd gear part?




isn't there?

it seems to spin straight onto the mainshaft...

so i only need the 2nd gear that sits on the countershaft??

right?

 

You need the gears on the main and counter shaft inorder to work. This is about the same as swapping the LS 5th gear in my b16 tranny. As long as the gear and pinion have the same diametrial pitch..you're good to go.

There is a set..the gear and pinion. Open up your tranny and you'll see.

 

mainshaft:



coutershaft:




notice that they come in a set. Crankshaft rotate mainshaft..mainshaft rotate countershaft...countershaft turns differential....differential turn wheel.

hmmm, so yes, there is the second gear pinion - it is a part of hte MAINSHAFT,

so i guess the answer is that i NEED to swap the mainshaft IF i want to run the ITR second gear?

well, that is good as i am swaping the mainshaft anyways so i can fit the 4.785 final drive...

sweet - thanks for all the responses peeps!

 

um, dude, those things that come in a set are syncro sleeves, not gears...

part '3' is the second gear

ummm dude, you are not getting the point....i didn't tell you to you change the syncro (goldish brown part as a set)...I am telling you to change the 2nd gear and pinion as a "set".

OK, the point is, there is no <U>seperate</U> pinion,

i have just worked out that the "pinion" that you refer to is actually part of the mainshaft.

and therefroe the "set" you refer to is the 2nd gear + the mainshaft.

 

I understand what you meant now. You are right...looking at the manual, it doesn't look like there is a speration point on the mainshaft for the 2nd gear.

However, being the that the second gear pinion and the differential pinion is on the mainshaft and you are swapping the mainshaft to install the 4.785 fd...I believe all you need to install the itr 2 second gear is to swap out the 2nd gear on the countershaft to an itr second gear and swap out the differential ring to mate the 4.785 fd.

This make me wonder how people swap out the 4.4 fd to the 4.785 fd but still retaining their stock gear ratio for 2nd gear? Maybe I am missing something

broswing through the internet a little bit... I think I may have found my answers. When people buy a "kit" for the 4.785 fd...it come with the second gear also.

 

The countershaft second gear is not included in the final drive reduction kits, only the countershaft first gear. I'm guessing that it's so that the first gear properly pairs with the countershaft to keep the first gear from either binding or being too loose.

You need to replace the countershaft 2nd gear and the mainshaft in order to get the ITR 2nd gear ratio. The countershaft does not need to be replaced when replacing the 2nd gear pair.

You also need to reshim the mainshaft every time the mainshaft or any one or both of the casing halves are replaced.

cheers! all i needed to know!

yep, called Mainshaft Thurst Clearance checking...

thanks again
