Recently, my '94 854 Turbo started to have shifting problems on cold mornings. When our night time temps dipped into the teens my car's automatic transmission wouldn't shift immediately. Typically I would have to drive 3 or 4 blocks before it would decide to upshift. The fluid level is fine and the transmission fluid has been replaced with Mobile ATF at regular intervals.

I came up with a couple of ways around the problem.

Solution 1: If I let the car idle for 5-10 minutes, most of the time it would shift fine right away.

Solution 2: If I put the gear selector in the "3" position instead of "D", the car shifts fine.

I never had to worry about the transmission before even in subzero temps. Has anyone encountered this before and is this an indication of a transmission that is going bad?
