Automatic slipping

[2ndwind]

After replacing the AFM (thanks George) and transmission modulator, it is now clearer what is happening when driving my "82 AT Spider. If I go around a 90 degree turn in 1st or 2nd at anything other than very slow speed, the tranny slips completely. No slipping going straight forward or reverse. Any insights?

sounds like low fluid, or a filter that has come loose inside the pan allowing the pump to suck air on turns

Thanks Mark,
I will do a proper check of the fluid level. As far as the filter issue goes, unless it is immediately obvious upon dropping the pan, I will probably have to take this to a tranny shop. I have learned here that it is a GM TH180, same guts as a Chevette.

Again, Thanks Mark,
Originally, I had checked the AT level in the garage with the car off, like checking the engine oil. I vaguely recalled ATs needed the engine in drive or something to check. Well, well, reading the manual (the directions when all else fails) I learned to drive it 6 miles, put in Park or Neutral, check while idling. It was 2 quarts low! Drives great now. Thanks for heading me in the right direction.
