How does the internal gear work on a GM 350?

The internal gear engages with two cut out slots on the end of the torque converter hub. The outer gear is offset in the pump to provide fluid flow and pressure as the pump turns. The pump tolerances are very close in the pump halves to maximize its efficiency.

Is there such a thing as passing gear?

Rod_Knox July 6, 2016, 5:23am #3 There is no “passing gear.” When you attempt to accelerate quickly the transmission down shifts to the next lower gear to prevent “laboring” the engine. When pulling away from a stop quickly the transmission will hold out the shifts to an appropriate speed.

What kind of transmission does a GM TH350 have?

Turbo 350 Transmission Specs. This transmission replaced the GM Powerglide automatic transmission, which was a 2 speed automatic transmission that was in production for 23 years.

When to put TH350 trans in second gear?

Seems a lot of TH350s were put in front of really long gears in the mid-late 70s, so they are calibrated to shift right with those gears. Put the trans in front of 3.73 gears, and it will get into second gear right away.

When did the Turbo 350 transmission come out?

The Turbo 350 transmission was introduced beginning in 1969. This transmission was a 3 speed automatic transmission developed jointly by Chevrolet and Buick.

How does the kickdown work on a Turbo 350?

The kickdown function of General Motors vehicles equipped with the Turbo 350 automatic transmission is perhaps better known as “passing gear.”. As the accelerator is depressed, the throttle lever on the engine is drawn back by a cable, which in turn pulls another cable attached to the transmission, causing it to downshift into a lower gear.
