How does the Chevy Express 3500 transmission work?

How does the Chevy Express 3500 transmission work?

The Chevrolet Express 2500/3500 was designed to handle heavy loads and heavy trailers. As a result of all this hard work, an excessive amount of heat can build up inside the transmission. The ATF is designed to absorb heat as it passes over the moving parts, then expel it as it passes through the cooling chamber at the bottom of the radiator.

What happens if my Chevy Express 3500 goes bad?

There’s a lot of moving parts inside of a 6L90 torque converter, and if one of them goes bad, you could experience symptoms like delayed shifts, slipping in-and-out of gear, no forward gear, and no overdrive. This tends to happen rather prematurely, creating one of the more common late-model Chevrolet Express 2500/3500 transmission problems.

Why is my Chevy Express not shifting gears?

If you hit the gas and your van slips between the gears, refuses to shift, or it doesn’t go anywhere at all, then you may have a failed 4L80E shift solenoid. These plunger-like devices are used by the computer to control the flow of pressurized ATF inside the valve body.

What causes a Chevy Express transmission to fail?

When a particular gear is called for, the computer sends electrical current through the solenoid wires, which causes the plunger to activate and direct the ATF to the proper gear set. Heat and vibration can make the 4L80E solenoids fail prematurely, leaving you with a non-working transmission.

Can a remanufactured Chevy Express have transmission problems?

If this happens, your transmission can experience all sorts of problems, including ruptured seals, damaged clutches, bands, and a warped valve body.
