1998 Honda Accord Computer issues vs. Trans. Car works fin

Transmission problem
1998 Honda Accord 4 cyl Automatic 130000 miles

My 98 Honda Accord EX A/T 130K check engine light came on while driving on highway. The car drives fine, until it sits over night. The next day the cars trans skips, & slips, creating red line RPMs. The mechanic cleared the 3 trans codes, the car was fine for 3 months. I just drove 100 miles, the car sat for 4 hours, the light came on. I had to drive another 200 miles & everything was fine, until the next morning. My shop cleared the codes again, car drives fine. Could this be a computer issue vs. Trans? B/c when it's winter the SRS light comes on until the car warms up, then it turns off. A month ago the ABS light came on after my car sat for 9 days but went away the next time I started my car. My oil gage on the dash board bounces and doesn't work "at all times". When I get an oil change at JiffyLube the computer always reads no oil but I have it. Can you help? Is it trans or computer? I know nothing about cars & need help. Please provide your guidance.I have no $ to fix or buy used.
