FWD light intermittent

My kids 97 outback has been giving transmission codes the last few days. The yellow temperature light will come on for two seconds like it should, followed by 15 fairly quick flashes. The car shifts and drives perfect except for a slight torque bind feel that was not there before. We put a 15 Amp fuse in the FWD socket, just in case it would prevent damage till we got to the dealer, and the light didn't come on. I attributed it to being part of the problem but left the fuse in feeling it could do no harm, and might help. After one day, the FWD light came on for one day. Since then, it comes and goes when it feels like it. It does not flicker, but rather will be on for a long time or be off for a long time. All connections are clean and tight! The real kicker, is dropping the car off at the dealer last night, The original temperature light error code has cleared and you get the normal two second test signal then nothing else. For that period at least, the FWD light is now solidly on! Car obviously hates going to the dealer, anybody seen anything like this?
