No time to watch the video at the moment, but this is the question I've been asking for quite awhile: What actually happens in the transmission to create tub indexing. It isn't just because there's no tub brake. Thanks for posting the video and hopefully a member fluent in the language will be able to clarify things.

WH TL Transmission Breakdown You can find anything on the internet, LOL
Torn down like this you can easily see why it was such a poorly designed and short lived washer, a ball bearing and a face type oil seal in the bottom of a gear case is the first disaster, all the metal particles that wears from the cast-iron gears etc will quickly destroy the bearing and seal.
The top main seal pressed into a pot-metal transmission housing is a short lived design as well, but the worst design bug was the water pump on top of the motor and the motor only had a carbon steel shaft which will rust and cause the seal to leak water into the motor destroying the motor and this usually happened before the transmission failed anyway.
The cost of replacing the motor and pump was so high back when these machines were popular that I never knew of a single one that got fixed when the pump seal failed.

it got worse when WCI took over....cheapened the whole machine, but still offering to sell at comparable prices to models like the Kenmore/Whirlpool/GE....when they should have been half of that...
plastic tubs, no tub brake....miracle the whole transmission wasn't plastic... in one of the models we took apart, there was a huge spring wrapped around the bottom shaft....I knew this was part of the indexing as with a broken spring, it would index in both directions.... but yeah, they could have added an internal brake like the GE FilterFlos.....even that indexes during wash startup until it locks in place... | ||

Why These Washers Index During Agitation It actually is just an accident, the torque spring is there so when the motor reverses to spin it grabs and the whole inner part of the transmission turns with the wash basket, as Martin mentioned GE Ff washers would index if they had not gone to the extra expense of having a brake.
Most new TL washers with lid locks have no tub brake and they index in both directions, but these WH-Franklin designs were worse because the basket was actually powered in one direction by the tension of the helix spring slipping on the hub.

If the indexing or ratchet effect is created by the large spring...clockwise stroke spring LOCKS...counter-clockwise stroke spring EXTENDS...what would happen if the spring is removed? | ||

Hmm, here's a video of a washer that needed the transmission large spring and transmission pulley small spring to be replaced CLICK HERE TO GO TO scrubflex's LINK | ||

Harry, John is right about that spring. The purpose of that spring is to lock the transmission components when it turns in the spin direction so the entire inside (gears and that big square gear base) all spin together without turning the agitate gears independently. If you took that spring out, during spin the agitator would oscillate like in wash and the tub would index back and forth in both directions. You'd never have spin unfortunately.
