What part is this? T-350

Quick question and no luck with searching.

On the 350, on the passengerside, there is a plastic piece coming out of the trans. It's right below the oil cooler lines, and sits closer to the pan. The part going into the trans is a yellowish/orange (color blind ) and is held in by a 10mm bolt I believe. I broke this off.

What is it, and where can I find one asap? Thanks everyone!

The piece below the Cooler lines would be the Detent/Passing gear cable. Connects to the Carb linkage. They're normally Black tho'.
Any Auto parts store should be able to get you one.

Ok thanks. Just want to make sure since the color is different

In this pic, it's behind the bottom fitting, going in at an angle, right about where the dip stick is. Still the passing cable? Is this also known as the kickdown cable?

The TH2004R & 700R4 use a TV/ThrottleValve cable, "The TV cable controls line pressure, shift points, shift feel, part throttle downshifts and the detent downshifts." Adjustment is very critical.

TH350 uses a Detent cable, only controls passing gear or kickdown. Can be eliminated but, downshifts will be manual only.

No, no, and no. The TH350 does NOT use a throttle valve. A throttle valve changes line pressure in relation to throttle position. On the Powerglide, TH350, and TH400 the vacuum modulator performs this function. None of those transmissions use a throttle valve. On the TH350 the cable is a kickdown cable only.

I've found that when putting a B&M shift kit in a TH350 (street strip mode) that leaving the cable disconnected provides a crisper 2-3 up-shift. Never cared much for full throttle auto down shift anyway.

joe p

your statement is only 2/3 corecct on 350/400.a powerglide does not get any shift timing from the modulator it controls line pressure only.shift points are from throttle linkage similiar to a chrysler 727.you can plug the modulator and it will still shift at same speed
