5 REASONS JDM CTR/ITR TRANSMISSIONS ROCK YOUR SOX!

1) Reverse Needs to be just as strong as any other gear.. Who knows! It might come in REALLY handy when you're running from the cops! =0 So they used a long shoulder Reverse anchor bolt that's ALOT stronger than the USDM performance counterpart on the left..

2) They have Keyed pinion shafts that have ALOT nicer alloy steel and keyed shaft to prolong HIGH RPM operation during long intense workouts!

3) They have Keyed Pinion spring washers! It may sound like jibberish.. But in fact, this washer is sandwiched between the 5th gear load bearing and the nut that holds the ENTIRE shaft together.. If it spins, the nut will follow.. That could be REALLLLLY bad!! The key in the washer prevents this from happening!

4) When you're slamming gears at 9,000 RPM the last thing you wanna hear or feel is the "nails on a chalk board" sound of gears grinding.. This is put in check by using FORGED STEEL shift forks (Right) where as the flimsy USDM sheet metal ones are known to flex under load.. (left)

5) EVERYONE will agree "LSD or NOT-LSD? IS NEVER A QUESTION!" Since it's a standard option on ANY TYPE-R, they are some of the most desired..

TYPE-R is more than just a HP number and a badge.. It's about superior performance..

Thinner or not, they're not made of sheet metal.

Sheet metal dosen't JUST refer to thin flimsy "sheets of metal"..

metal is refered to as "Sheet" because thats the form it takes before it's made.. It's a large piece of steel that is flat and has uniform thickness.. Sheet metal can refer to 1/4" (.250") thick sheet metal.. Would you rather I say "Plate"??? It means almost exactly the same thing.. Learn to use a dictionary..

"sheet metal." WordNet® 2.0. Princeton University. 03 Oct. 2006.
<Dictionary.com http://dictionary.reference.com/browse/sheet metal>

Anyhow, if you couldn't tell, the "SHEET" of steel is stamped into the shape of a shift fork then welded to the shift rod and slightly machined then coated.. The design was simple and cost effective since forging steel is alot more labor intensive and takes more resources to produce..

The shafts are VERY similar but I was also noticing that the 1-2 shift fork on the USDM version is 3 pieces whereas the JDM-R Version is 2 piece! That's one of the most abused pieces in the whole shift assembly and in the JDM version, it's one of the strongest pieces!

me too i have ctr but third grinds

when i rebuilt my us gsr trans, it had the jdm style shift forks. . .

Stinkycheezmonky · 10-04-2006, 05:27 AM

Sheet metal means a sheet of metal, like the kind you buy at Home Depot. That implies extreme flimsiness. Stamped metal would've made sense, as there are lots of stamped pieces, like ITR LCAs. I don't think I've seen anyone complain about how weak and flimsy those are.

Hmmm, I have read this befor somewhere. Either way, good info

Rene M · 10-10-2006, 10:30 PM

a)I can say i have never found shift forks that look like that in an s4c or an s80.....
b)I can say that CTR lsd from what i have learned is not very reliable and the thorson works much better "Personal extreame track use experence"..
c) the forks/deep slot on the shaft and the reverse bolt are all found in 99 and up s80 and s4c trans. you left out the new design of the reverse rear which no longer has a shim and is an all cast piece " hense the odd bolt"..
there are at least 6 other diffrences in the late model Hydro trans that i can also point out if you would like. These are the result of failures in the early hydo design not and effort to build a better trans to run from any one "the ctr lsd was dropped due to its weight and the fact they burn up" " on another note the ctr lsd eats 8% more hp up due to its much heaver weight which is why the ctr's #s were lower than expected.
I can go on but its late.
