I have a b18c1 and my tranny grinds 3rd and 5th gear. I was wondering what my options were?

Replace the gsr tranny.....

Buy a Type R tranny.....

Or, rebuild my current tranny with LSD....

How much would rebuilding the gears with LSD run me $$ ?

I know I can save up for a type r tranny as long as I save my $$.
So money isn't an issue as long as this tranny holds up.

 

Your problem is most likely just a couple of worn syncros. I would buy a Quaife diff, have a transmission shop fix all the syncro issues and install the diff.

 

If you aren't going to make more than say, 300whp or so, I would go with an R tranny. A Quaife would be better, but they run $800 for just the diff. Then add the costs of the worn tranny parts, and labor and your price is going to increase significatnly. If you're going to stick with an N/A build, the R LSD should hold up fine. You can get a 4.40 R tranny for $1200 or so. You'll have shorter gearing, and you'll hace an OEM LSD. You can get a 4.785 tranny for even shorter gearing, but that'll cost $1500 or so.

 

Yea, actually that does sound like the best route. After I think about it....

MY only question is with that last gear, I know everyone wants the longer gear for 5th ? How annoying is highway driving with the stock gear ratios ?

 

Compared to a GSR tranny, the 4.785 FD gearing is about 10% shorter through all the gears, which means cruise RPM would be 10% higher(your current cruise RPM+10%). If you're still running your stock single-core radiator, and you like to cruise at higher speeds, that may be enough to bring you close to overheating the puny Civic radiator. You may want to look into a dual core alumium Civic radiator, or a wider Integra radiator, especially if you like to cruise at higher speeds, and run your A/C or something.

 

A transmission's final drive (FD) gear is not any one of the speeds. Each of the gears one1 through five has a numerical ratio of how many revolutions of the motor it takes to turn the wheels once. From there, the FD connects the gearbox to the differential. The FD also has a numerical ratio, which means it multiplies the ratio of whatever gear you're in.

If you had two hypothetical transmissions, one with a 4.400 FD and a 4.785 FD but otherwise identical, each of the gears in the 4.785 FD transmission would be effectively shorter because of the higher FD ratio.

 

ah ok, that makes sense. Yes, I dont mind a longer 5th gear, in fact I would prefer it for highway driving......

Now, if I could just get my dirty hands on a Type R tranny...:naughty:

 

WHAT EXACTLY will you be doing w/ your car?? Road race? Autox? drag racing? How frequently? obviously daily driving.

The 4.785 FD jdm tranny also has a shorter final drive than the 4.4 USDM one.

 

most street racing, and track....and daily driving
