5MT Transmission swap!!! BD/BK/BG 5MT -> BE/BH 5MT

[chuckthefuk]

I don't know what it is with these damn 3rd generation 00-04 legacy transmissions but they seem to develop crippling issues.

I have two friends with a somewhat identical 00/01 GT 4.11
Issues:
- 3/4/5 gear pops out during deceleration
- extreme whine/vibration
- center diff explodes from vibration

So I have gone through hell and back trying to obtain solid facts/photos/info about swapping a older legacy generation 2 transmission into a generation 3.

After hours on end I finally received a "go ahead" from the man himself "JoeT"

FACT! -> All Subaru 5MT " TY75*********** " transmissions are interchangeable
Source-> http://spda-online.ca/modules/tinyconte ... tc_28.html

FACT! -> ALL Subaru 5MT/6MT use similar style VSS (Variable Speed Sensors aka Speedometer Sensor)
FACT! -> ALL Subaru 5MT/6MT VSS can be interchanged. YOU MUST USE THE VSS FOR YOUR GENERATION BODY HARNESS!
FACT! -> ALL Subaru 5MT linkages can be interchanged.
FACT! -> Pre-98 5MT use 4x bolts on the bell housing. 98+ use 8x bolts. No matter either will work.


So here's the combination of items I used and the info break down with some pics ;-D

Transmission:
Original -> US Legacy GT MY01-02 TY754VCBDA 1.000 4.111 Viscous (4kgf) Open
Donor -> US Legacy GT MY97 TY752VACBA 1.000 4.111 Viscous (4kgf) Open

Note
Pre 98 transmissions use 4 bolts in the bell housing.
Post 98 transmissions use 8 bolts in the bell housing.
--> Makes no difference.. bolt and go!




Variable Speed Sensor (VSS)
- The 01' VSS had be installed into the 97' in order for the 01' harness to connect to the 97' unit.
-> Simply unscrew and reinstall.



01'


97'



Linkage:
Installed 01' Linkage onto 97' Transmission or vice versa..
--> The linkage update made the 97' feel like the 01'. If anyone has ever driven 02' GD or 00' BE/BH then you will understand.

Driveshaft/Propeller Shaft:
Installed a 97' Legacy driveshaft into the 97' trans connected to the 01' 4.11 R160.
-> Yokes are the same
-> Bolt pattern is the same
-> Center bearing hanger mount is in the same place and use the same bolts
-> The gen 2 is very different then the gen 3 but dimensions and installation are identical. \

Gen 3


Gen 2


Clutch/Flywheel/Pressure Plate/Slave Cyl/Release bearing/Fork
- Clutch/Flywheel/Pressure Plate/Slave Cylinder are 01' units.
- Release bearing and clutch fork are 97' units.

Axles
- Used original 01' BE axles with 97' unit.
-> Same jazz ... pop out the pin pull the axle out your good.
NOTE: some BE/BH use axles that have the abs ring on axles instead of the spindle.. be sure to check if your attempting to use gen 2 axles.

Standard Subaru trans/gear oil... turn her over.. off you we go..

Anyways I hope this gives someone hope for their stupid expensive gen 3 tranny.. BD/BK/BG's are so damn cheap that you can usually buy the whole car for the cost of 1 used BE/BH tranny :-D

Back to work i go before I get fired :-D


---- Update ---

Below are pictures of another transmission swap.

Original: 2000 Legacy GT 4.11
Donor: 1998 Legacy GT 4.11

Same deal..
98' LGT 4.11
98' clutch fork / release bearing
00' clutch/flywheel/pressure plate/pilot bearing .. This is Bataru's car he has an upgraded Bully Stage 2 clutch.. easy peasy..
00' driveshaft/propeller shaft!
98' JDM STi v.5 shifter & linkage
Group N tranny mount

fill'er up and go!

I have a 00 Legacy GT wagon, recently my driveshaft tore apart at the u joint. I thought that all subaru 5MT should fit as a replacement. i picked one up from a local guy, but it was significantly shorter(im thinking it was auto or 6 spd).

my question: should any subaru 5MT driveshaft fit for my needs? IE wrx, rs, older legacy. these are more available than 5spd BE ones

You need a bd/bg or be/bh 5mt legacy drive shaft. Impreza or Forester won't be the right length and Outback will have the wrong center carrier bearing.

what about bp/bl?

[nepbug]

what about bp/bl?

I don't know for sure, but would lean towards no. There might be some length measurements out there somewhere you could use to check, or maybe even in the FSM. I've got personal experience mixing generations between BD/BG and BE/BH though and know that for certain.

cool thanks, just found a BH shaft on ebay so that should do it
