Here's some updates. I tried swapping the speed sensors (on the trans), no help there. Here's some more info, my scan tool is informing me I can't get the torque converter to lock, and ordinarily I can force the solenoids to lock; and they will not. Also, if I rev the engine over 3 grand the flashin...

Bah, still no luck. My scan tool tells me the transmission speed, so that's a good sign. My tool allows me to activate and deactivate certain solenoids in the trans, and none of them listen to me. I'm going to see if I can find another TCM...

This is awesome news. I have tried a couple of mediums, However I scanned with "PC Retriever" and "Autologic". At one point I did have a code for 2 speed sensors. I shook them off as I am accustomed to Saabs (where the speed sensors are in the wheels, not the trans) but now it ma...

I know this an old thread, but I'm quite happy I found this. I'm trying to tackle a flashing trans light, and I've tried the PNP, ABS Unit, Winter Switch, the whole nine. I have no trans codes, however I havn't driven the car far without the use for 1st or 2nd gear. A shop put a used trans in before...

So I put a rebuilt ABS module in (we had one in stock) and it did not help. One additional bit of info I have found is the positive battery cable gets screaming hot when the car is running. Not sure if that is common or could possibly be a contributing factor. I figure the more info I give the bette...

Hello again all, I figured I would take a video of what is going on as a picture (or moving pictures in this sense) are worth a thousand words. Still look likes it needs an ABS module? Note how when I go from L to D the light is off for a few seconds and then begins flashing away. I was incorrect wh...

One more questions before I begin pulling this guy out to have him rebuilt. When I pull the connector to the ABS module, the UP arrow flashes the same, however the ABS light comes on. I plug it back in, and the ABS light shuts off and the UP arrow continues blinking. Still sound like the ABS Module?...

That's strange I don't have any other codes, however I imagine because the battery has been dead it doesn't hold many codes unless you drive it. Does that sound plausible?

Good to know. We do ABS Modules constantly for Volvos, can a bad ABS module cause the flashing up arrow AND the trans starting in 3rd? The tech working on it says the trans is mostly happy, however should be throwing gear ratio codes but isn't... My diag guy said the up arrow is flashing very strang...

Thanks for the replies gentlemen. Here's some more information: 1. The ABS light was on for two wheel speed sensors, I cleared the codes and they did not come back. 2. The scan tool is showing that the gear selector switch is in the correct corresponding spots (P, D, N, ect). 3. There is one code in...
