Thanks Spook.
The volvo sensor is backordered everywhere. The aw30-40LE transmission is used in many Toyota vehicles. I grabbed a new sensor for an 05 Sequoia and spliced it in (it ohm'd identical to the volvo one) and no change in operation. I believe I have narrowed it down to the speedometer head.
I was combing the wiring diagrams and there is a grn-blk from the speedo to the TCM and a grn-blk from the transmission speed sensor to the TCM. The asin-warner documentation for the a340e says the speedometer mounted rpm sensor is primary and the transmission is secondary/backup.
I think I am going to try jumping the two wires together to see if that bypasses the dead speedometer. I am also looking for a 92-94 instrument cluster to swap out. If I can get a 94 then several of the volvo dealerships have new replacement speedometer heads in stock (per their websites).

Anybody know if those grn-blk wires carry the same signal / pulse count? I don't have a fluke, or a working speedometer head either...
