I'm looking for a definative list of tranny codes and ratios, if you know them, then paste them here please, or post a link. Hybrid Racing have the specs up, but not the codes...

for example, euro CTR is designated "Q3" - correct ?

Also, how do I tell if an LSD is fitted ? (axles removed).

I have been offered a JDM CTR tranny, just need to make sure its the real deal.

TIA.

Joe,

simplest way is to look though where the driveshafts fit in, if you can see the diff centre bar, (and then out the other side) then there is no LSD

02-04 Type-S is X2M5.

What the heck is the K20Z1 tranny code??? Anybody???

Does anyone know if the 2005 ITR trannies were changed as well??? We have an ITR tranny that would not fit the Hasport mounts.

Also, Does anyone know the TSX and/or Euro ATR tranny code???

I gathered some part numbers for the K20A2 and the K20Z1 but not the K20A.


Now my question is, if I bought the K20Z1 tranny internals (final drive and LSD), would they fit into the K20A2 tranny case? For the K20Z1, the LSD can be bought for about $223, the final drive for $136 from an acura dealer. Could this be a "cheap" solution to getting a "Type R" tranny on a K20A2?

Here is the link where I got my prices: http://www.acuraoemparts.com/delray/jsp/prddisplay.jsp?inputstate=5&catcgry1=RSX&catcgry2=2005&catcgry3=3DR+TYPE-S&catcgry5=MT++++++DIFFERENTIAL&ListAll=All&vinsrch=no
