Lost 2nd gear and overdrive

I lost my 2nd gear and overdrive in my 1995 chevy silverado today. It has an electronic tranny. any idea's? 1st drive and reverse work.

2nd Gear and 4th (Overdrive) both have the 2-4 Band applied. If you lost both of these gears, the 2-4 Band is slipping. Tranny needs to be removed and rebuilt to repair this failure.

Could it just be the solinoid?

Could it just be the solinoid?

with a transmission this old and past reports of failures this would be a rebuild job..

what are your transmission fluid / filter maintenece intervals ...?
did you just purchase this vehicle? what does the fluid look like ?

A scan with a trans function would reveal whether the solenoid is active, but j cAT's advice is correct.

2nd and 4th do not share the same solenoid.

For 2nd, the A solenoid is OFF, B is ON.

For 4th, A is ON and B is OFF.

When it is suppose to shift to 2nd, does it feel like it goes into Neutral or does it stay in 1st?

If you have lost 2nd and O/D but reverse is good then the issue is with the 2/4 band or band servo. The servo could be leaking or the band strut is broken. I would check the pan for debris. This is not an electrical problem.
