I blew out my 4th gear of my 02-04 type s trans back in January, installed another 4th gear set from my buddy's old transmission with low miles that he didn't abuse... It lasted about 4 months and it blew out again.

I'm making 560 whp, torque comes in late and smooth with a big laggy turbo. It's strictly a street car. I make a lot of pulls in it, but I know of countless guys who run stock ep3 transmissions with more power and who abuse it more that have lasted for 2-3 years....

Am I missing something? I've used two types of fluids now with no luck. First time was OEM MTF, and second go around was Torco RTF. If all transmissions are ticking time bombs at my power level and above, how long would a PPG or Albins 3rd and 4th gear last me? I don't want to spend a couple grand on something that'll break early down the road.


Suggestions, imput?

strictly a street car i bet a liberty/albins/ppg would last several years without any issue. ALBINS has the biggest bang for the buck with their synchro gear set as far as street is concerned. .

i've read a few guys who daily on gear sets without synchros. IE: subaru guys. why do we have synchros if others don't use them on aftermarket gears?

WHO SAID YOU HAD TO USE SYNCHROS?

^^^ some random people suggested syncs on a tranny that is driven on the street.. but i also asked myself your questions.. WHy do we need themmm?

Best thing to do is buy brand new gears and have them treated by racer steve. My type s tranny lasted 2 months at 700+hp, i blew 4th gear then 5th. I bought brand new gears and Had them treated and put them through major major abuse and sold the car but tranny is still holding up. Used gears arent goin to last because most have been abuse or have small stress cracks from things like running low on fluids or people not changing fluids in there trannys regularly. The gears are cheap and it is def worth the money to just buy new ones strait from honda. And will even be more worth your while to just go ahead and have em treated.

Synchros make driving on the street a whole hell of a lot easier lol

the type of fluid is huge.

just invest in a good gearset like ppg or albins and never worry about it again. sure, the initial price is huge, but in the long run it will be cheaper when you're not rebuilding the tranny every few months.

my buddy is making ~800whp in his 8th civic and finally went with albins gears after going through numerous gears and final drives.

Your driving style is most likely wHy your breaking gears. Some people break gears and 200whp and some people don't break gears at 1000whp

What fluids did you use?

How old are the bearings?

How much endplay did the mainshaft gear have once installed?

What was the mainshaft thrust clearance?

Was the install height of the countershaft gear in relation to the mainshaft gear at the same install height as that of the old trans?

Only mentioned that last one since it was a previously used gear set mixed into a different case.

Just my personal opinion is that driving style and fluid used seems to make a big difference in how long they are going to hold together. Also, some people seem to look past or not pay attention to a transmission when it is making noises it should not be making (ie a bearing going out).

I have been messing with Hondas since 1997 and have only had one tranny break on me in a car making upwards of 400whp. The stock diff in a tranny that had never been apart broke and destroyed a bunch of stuff including the case.

I have been in more than a few Honda transmissions B, H, and K series. Once they were all together I recommended using a mix of Honda MTF and Penzoil Synchromesh. Always used it in mine after doing some reading on it years ago and it seemed to work really well and so I spread the word and all of my friends who I have fixed transmissions for. They seem to like it too. I have never broken a gear in a transmission personally and always chalked it up as I was never making enough power or not racing on the track enough, but then I see guys breaking stuff at 250whp.

I know clearances and what not within the tranny are important, but I have seen some thrown together with spare used parts and work fine with out checking anything much other than that it shifted once it was together. Same with engines though. Someone can throw together some junk in their backyard and it holds, then someone else can measure and remeasure everything and assmble it with TLC and it will blow.

The only problem with buying a gear set, or even just a 3rd and 4th gear is that if my plans of making more power down the road and my 24.5" slicks run out of MPH, then i'd have to buy new gears or final drive.. I have the money, i just can't decide on what ratios i'd purchase. WWJD? haha

I drove around on 220 whp for about a year and a half, and then put on a 75 shot on it and drove it pretty hard, power shifting.. etc. so i don't blame the first 4th gear breaking on me

2nd go around i used Torco RTF
Bearings were new (bought a complete rebuild kit from synchrotech)

All the endplays and clearances checked out to factory specs whenever we reassembled the motor

One thing we didn't look at closely was the install height of the counter shaft gear and mainshaft. What if they are off? do you shim one shaft so they are of equal heights?

i'm thinking of purchasing some brand new gears and having them treated.. hmmm
