CIS Subaru Posted March 18, 2004 Share Posted March 18, 2004 Does anyone know if all EA81 and EA82 transmissions use the same speedometer gearing ratio? I've been thinking about attempting to use a 120mph EA82 speedometer in my EA81 DL cluster because I'm already going to add a tach, and I hate being able to peg the speedometer. I just didn't want to get into it and find out that it would be reading wrong when I got done. Link to comment Share on other sites More sharing options...
mcbrat Posted March 18, 2004 Share Posted March 18, 2004 the cable can be specific to the trans. ShawnW had to use a RX cable for his FT4WD tranny. the ea81 cable would not work. fitting was different Link to comment Share on other sites More sharing options...
CIS Subaru Posted March 18, 2004 Author Share Posted March 18, 2004 That's certainly something to consider, but if I'm not mistaken, I think his problem was on the tranny end of the cable. I'm looking at using an EA82 speedometer with an EA81 tranny, so I really just need to know if the cable will be turning the proper speed to make the gauge read correctly.

ShawnW Posted March 18, 2004 Share Posted March 18, 2004 I would assume since my RX trans speedo is supposed to work with my ea81 speedo that the reverse would work too. The ends are exactly the same on the cable at the gauge end, and NEARLY the same on the trans end just a plastic disc is there on the ea81 cable that isnt on the ea82 one. Same size little metal tab is being turned and everything. The ea81 cable just wont thread down into the hole cuz the threads are too far up the cable.
