Saturn sl2 automatic transmission first gear only

My car is a 1998 Saturn SL2 , automatic, A/C, 100,000 miles
The valves body have been change at 60,000 miles. Since then, no problem with the transmission.

This morning, i drove about 15 miles on Hyway, when i got out, i stopped at a red light. When it turn grenn, i started, the transmission made 1 gear ok, but when it shifted in 2 gear, the engine stated to rev like it was in neutral. I stopped and chek the oil, it was ok. I also checked the fuses. At home, i checked the codes, those 3 code appear: 732, 733, and 734 . Now the only gear working is first, no reverse and no 2,3,4 gear. Any idea what is the problem?

Check your alternator, battery, battery connections, grounds and the big plug on the top of the transmission. You might have to remove the air box to see it.

This morning, i started-it and all gears were working. I suspect it is somting temperature related. So i have replace the temperature sensor and the connector, it was oily, may be leaking. Another parts is sometime affected by temperature : selenoid valves. On my last saturn sl1, a selenoid valve was defective when hot. Cold it as 4.9 homs and hot 2000 homs. the tranny was slamming in third gear. I would like to know if 1 of the selenoid valves can affect all gears eccept the first??????
all c electrical connection, battery and charging system have been checked OK
