There are 3 foreward gears and 1 reverse gear.
A turbo 350 has only 3 gears. The 700R4 has 3 gears plus over drive and lock-up converter. And it is the same as a 400 turbo with overdrive.
A Turbo 400 transmission typically has three forward gears and shifts a total of two times as it transitions from first to second gear and then from second to third gear. It operates in a simple three-speed configuration, meaning it does not have overdrive or additional gears beyond these three.
You are probably thinking of the turbo hydro, 350. It was Chevies base automatic, after the powerglide. It had 3 gears, and was fairly tough. The turbo 400, was the heavy duty version.
There's only one type of 400 turbo.

the 400 turbo is made for more pulling that's whats in my 85 gmc 2500 its just a heavy very expensive transmission.

The 350 turbo is a good transmission but the 400 turbo will take more abuse.
The Turbo 400 (TH400) transmission is generally about 2 inches longer than the Turbo 350 (TH350) transmission. This difference in length can affect fitment in some vehicles, especially in tight spaces. Additionally, the TH400 is a heavier-duty transmission, which is another factor to consider when comparing the two.
No, a 4L60 transmission cannot directly interchange with a Turbo 400 transmission. The 4L60 is an electronically controlled four-speed automatic transmission, while the Turbo 400 is a three-speed automatic transmission with a different design and shift pattern. Additionally, the mounting points, bellhousing, and driveshaft configurations differ between the two, requiring significant modifications for an interchange.
