I Donated broknindarkagain Posted September 20, 2011 Author I Donated Share Posted September 20, 2011 (edited) 5MT There have been several variations of the 5MT. Between 1990 and 1995 model years, only the turbo vehicles (USDM Legacy Turbo) had a hydraulic clutch. 1995 and later, every 5MT had a hydraulic clutch that used either DOT3 or DOT4 brake fluid. In 1998, Subaru changed from a push type clutch to a pull type. Minor bell housing changes were needed to make this happen, but transmissions are still interchangeable with each other. The 5MT uses a 50/50 torque split. 5MT Used in pretty much all Subarus from 1995 - 2002 including the WRX) 1st : 3.785 2nd : 1.945 3rd : 1.500 4th : 0.994 5th : 0.780 - 0.735 WRX Final Drive : 4.11 - 3.90 WRX 1996 Exception 1st : 3.545 2nd : 2.111 3rd : 1.448 4th : 1.088 5th : 0.825 (FWD) - 0.780 (AWD) - 0.871 (Outback AWD) Final Drive : 3.454 (FWD) - 3.900 (AWD) - 4.111 (Outback AWD) 5MT Revised This transmission is used in all non-turbo Subarus 2003 - present 1st : 3.454 2nd : 2.062 3rd : 1.448 4th : 1.088 5th : 0.871 Rev : 3.545 5MT Turbo This transmission is used in all 5MT Subaru turbo cars 2003 - present 1st : 3.166 2nd : 1.882 3rd : 1.296 4th : 0.972 5th : 0.738 Rev : 3.545 Edited August 22, 2012 by broknindarkagain -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

I Donated broknindarkagain Posted September 20, 2011 Author I Donated Share Posted September 20, 2011 (edited) 4EAT under construction The 4EAT is the only automatic transmission available in the BD, BG, and BK Legacys. "EAT" stands for "Electronic Automatic Transmission". The 4EAT was released in 1988 for use in the Subaru XT6 and Leone Touring Wagon. In 1989 when the EJ engine was released, the bellhousing was changed to accept the newer engine, but for the most part the transmission stayed the same. The 4EAT has been used in the following Subaru models : 88 - 91 Subaru XT 90 - 04 Subaru Legacy 92 - 97 Subaru SVX 95 - present All Subarus The 4EAT design has been shared with a few other manufactures as well. Jatco designed the 4EAT, and has allowed Nissan, Ford, and Kia to use the same or very simular designs. Gear Ratios 1st - 2.785 2nd - 1.545 3rd - 1.000 4th - 0.694 reverse - 2.272 Final drive ratios vary depending on year and model. The majority of final drive ratios are 4.11 Common 4EAT Problems & Solutions Torque Bind This is probably the most common 4EAT problem. This is the transmission getting stuck in a 50/50 power split now allowing for slippage in the center diff. Its usually caused by a faulty Duty C solenoid, however can sometimes be cured with a few "drain and fills" Edited August 22, 2012 by broknindarkagain -broknindarkagain My Current Project - Click Here COME AND TAKE IT "The only thing necessary for the triumph of evil is for good men to do nothing."

I Donated broknindarkagain Posted September 20, 2011 Author I Donated Share Posted September 20, 2011 (edited) Thanks for removing the post! 5EAT wasn't standard equipment in the second gen Legacy so I'm not going to give it its own section. I'll touch base on the 5EAT and 6MT in the "swap" section.

lulzcow Posted September 28, 2011 Share Posted September 28, 2011 Despite my car coming with a stage 1 clutch, as well as lightweight flywheel; it appears no real maintenance has been done. I would really like to update the fluids in both my differential, as well as the transmission. I found the guide's portion of which fluids I should check, is there a guide somewhere on how to actually replace the fluids? I have a 5MT. (I did a search and the best topic I found was "5eats rule!") Link to comment Share on other sites More sharing options...

oregonlemondiesel Posted December 19, 2011 Share Posted December 19, 2011 Just picked up a 97 LGT with 5MT. Previous owner informed me of the 2nd gear syncros failing. It grinds going up into second, and down into second is near impossible unless I double clutch and match RPM. Redline 75/90 NS in the trans. Should I replace with the Subaru Special S 75W-90 GL5, or is it a lost cause? If syncos are done, my thought is just replace the whole tranny. It has 150k and rebuilding it would cost more than a new one. If I replace, should I just go with a 3rd gen or WRX tranny? What years will bolt right in?
