4L60E Introduction, Mechanical Operation and Powerflow

This is the first of five videos surrounding the 4L60E. The other videos cover overhaul information, electrical and hydraulics. In this video, I introduce you to the most common transmission in the US. I talk about the applications, construction and powerflow of the planetary gearset.

The Explanatory Videos Accompanying
your descriptions are only playing for
less than a second on my Device 😮

I see what’s going on. Thanks for letting me know.

@@siuautomotive Other than that they are Most EXCELLENT
Videos, Very detailed and Explanatory. Thanks for making
them 👍

@@siuautomotive any update on the explanatory videos? Im sure they contain great and beneficial informations and I would love to view them.

[@badboyee2hotmailcom]

Nevermind 😅 i dove into your basics videos. I am learning so much! Thank you for your time making these videos, they are absolutely fascinating!

At 34:33 There could also be shown a line from
Reactionary ring gear to transmission casé
indicating parking pawl holding rear drive
wheels stationary ¡¡¡¡

I always wondered, what would you get if you re-routed the hydraulics such that the reverse input clutch would apply in third gear in addition to the 3/4? Would that relieve the beating the latter gets?

[@siuautomotive]

That would help third, but that housing needs to be held in 4th. It would be tough to time the apply and release of the rev clutch just to benefit 3rd. There are some good performance options, like the drum at 4l79.com or the sonnax smart drum. Www.sonnax.com

At 25:54 I think you were in error, you showed the lo roller clutch working on the reactionary ring. Is should have been the planets inside circled as the reactionary ring is connected directly to the tailshaft/wheels ¿¿¿¿

Is the resource "Diagnostic Scenarios" available to the public?
