classact2575 Posted October 31, 2007 Share Posted October 31, 2007 I vaguely recall someone saying that Subaru put in ATF indicator lights starting a certain year, but I'm not 100% sure. My '93 doesn't appear to have one (or it's burnt out ), but I wanted to check with the experts first. Thanks! Quote Link to comment Share on other sites More sharing options...

I am not sure about the Impreza's but my 92 and 93 Legacys both have it and mention it on the driver side sun visor... I would look up there and see if it has the notice. I think it might have only been installed on AWD vehicles as well Quote Link to comment Share on other sites More sharing options...
rverdoold Posted October 31, 2007 Share Posted October 31, 2007 I vaguely recall someone saying that Subaru put in ATF indicator lights starting a certain year, but I'm not 100% sure. My '93 doesn't appear to have one (or it's burnt out ), but I wanted to check with the experts first. Thanks! I was thinking the same with my FWD '91 legacy. The 4EAT works fine (after rebuild) but the light doesnt come on at start sequence. I did some searching. FWD automatics do not have the light (also in dutch manual) AWD automatics have. So FWD no light (i checked mine and actually there was not even a bulb present) Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted October 31, 2007 Share Posted October 31, 2007 Here's a few excerpts from the http://www.endwrench.com 4EAT phase I article: The light controls indicate operating conditions to the driver. They indicate the POWER mode, manually selected 1st or 2nd gear, or hot ATF (AWD only). On 1990 and later Legacy models, the light controls indicate hot ATF (FWD and AWD), gears 3 -2 - 1, MANUAL mode and POWER mode. ATF temperature warning light was used on AWD vehicles only indicates overheating ATF. See description of TCU inputs for control unit logic in response of hot ATF. The Power indicator was a frame that illuminates around the word POWER on the combination meter. Activation logic of the power mode is the same as later models. ATF temperature warning light is provided on both FWD and AWD vehicles. It is activated by the TCU indicating overheated ATF.The TCU logic will shift the transaxle as if in the power mode, moving more ATF volume through the cooler. The indicator light was discontinued in the 1993 model year, but the logic for controlling hot ATF remained. Starting in the 1995 model year, the HOT ATF indicator light was reintroduced. It performs the same as in the past, with an added function.When the vehicle is started, it is lit momentarily. If it is flashing when the vehicle is started, this indicates the TCU has detected an electrical failure. When the TCU is programmed to do so, it will flash a trouble code to assist in diagnostics.

rverdoold Posted November 1, 2007 Share Posted November 1, 2007 now i get confused. So it means that i should have an ATF light which should come on at the start sequence??? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted November 1, 2007 Share Posted November 1, 2007 Oh I didn't take note of your location. The endwrench info is valid for U.S. and maybe Canada spec vehicles only. It might apply to soobs built for other regions but it can't be guaranteed. Quote Link to comment Share on other sites More sharing options...

Ah ha! That's where I read it. Bummer, though. I was hoping to try the "secret handshake," but I don't think it'll work... now to tear apart my car to find the ECU and mess around with the multimeter to figure out WHAT'S causing my [extremely slow] torque lockup to not kick in... :-\ Quote Link to comment Share on other sites More sharing options...
