Some more info... - Saabnet.com Bulletin Board
Using specs I found at transtec, I checked a few things out. Speed sensors both have 400 ohms (spec is 300 to 600) and all three solenoids are 14-15 ohms (spec is 10-15. That seems good.
I hit up Harbor Freight to grab a stethoscope - I can easily hear the shift solenoids click, and they are definitely only clicking half the number of times the "repeat" setting is set at. Additionally, I hear nothing, ever, from the lockup solenoid. I may not be able to hear it, but it's just a couple inches from the shift solenoids, so I feel like I should.
I don't know if a failed lockup solenoid would prevent a shift into 4th... seems unlikely.
If anyone has an automatic car and a Tech 2, I would be grateful if you could also run these tests and see what you're able to hear - both on the cycle count for the shift solenoids and the audibility of the lockup solenoid.
