OK, thats what happened - drove ca 100miles to car show, last 10miles tranny started slipping, lost OD, then 3rd, 2nd, 1st, some amount of fluid poured out from breather tube. No gears at all.

Next morning - looked fluid level, was high, get normal when started engine(so pump is working). Fluid was clean, no burnt or anything. Took a chance and drove home (100miles) - no problems, all gears worked fine.

To days later (yes, checked fluid again - was OK) - drove 20 miles, lost all gears again. When i shut down engine and start again after 10 seconds, all gears are there for next 2...3 minutes. And so on and so on.

No codes on my ELM/torque tester. No "insert coin" light on dash.

Push-button AWD, 1998 350 Vortec.

Can you guys recommend something wise, before i start tearing tranny apart?
