Ulu, Good explanation of the overdrive operation.I've found the following diagrams helpful.While they are in my Ford overdrive manual,the operation is the same as Chrysler. Also the video on youtube -" Chrysler Master Tech - 1952, Volume 5-6 Automotive Overdrive Controls"...☺️

I kinda like some of current country music... Oops! Point taken - not on playlist. 🙂

...Always beware when asking for an opinion...How about this, (borrowed image from Nickpick), "Mad Max Furry Road" 😉

This is the facial expression of a grumpy old man.....

This is the area where my wife and I chose to retire... https://www.youtube.com/watch?v=zo_vJl6dDx0

NAPA GL1 seems to perform okay in the transmissions of my old cars, never had a problem shifting using it to date....☺️

Back in the 60's I owned a mid 50's OHV V8 powered car using hydraulic lifters that developed an annoying and persistant tapping noise. I was using the best Shell engine oil on the market at that time, (the higher priced stuff),so it wasn't that I was cheap on either the product or neglecting maintenance. I don't as a rule use any additives or a lubricant that promises that it will cure a problem that may arise be it in the engine or transmission. As far as one lubricant being better than the other, I am more interested in buying the steak rather than paying for the sizzle...That said I bought a quart of Rislone and added to the crankcase oil and within a very short time with the engine idling the annoying tapping noise completely disappeared. Rislone at that time came in a metal can rather than a plastic bottle,not sure if the formula is still the same.I only used it that one time and it did the job...🙂

I use Firefox and Norton Safe Search...that way I avoid the news page that used to appear when I switched on my computer...Anyhow there is a very tiny square balloon at the bottom right hand corner of my screen and the occasional "ding" that signals there is a new headline from microsoft news to which I very seldom respond. So,this morning my curiosity got the better of me and I clicked on the balloon...The latest news here in Canada is that lock down restrictions are being eased while how the Covid 19 virus is being spread remains a mystery. What caught my attention was this headline... Also watch: Can COVID-19 be spread through flatulence? Needless to say I avoided the temptation. Hard to make this stuff up... LOL

I just follow the book..😉

In the original owners manuals for the older cars I have, there is a cautionary note, do not use lubricants with EP additives in the transmission...GL1 oil as mentioned is still available at a reasonable price...🙂

So,I'm skimming through the thread, and I read, "... was pretty common for people,girls to carry 45's " and I see a snapshot from "Easy Rider"...Right off I'm thinking guns and MackTheFinger musta grown up in a pretty rough neighbourhood.LOL

Keith, It is not available at NAPA in Canada...They have never heard of it, (blank stare at the counter), lol. I live not far from the US/Canada border,I phoned the NAPA dealer in Cut Bank,Montana...trucked from Billings,Montana, it was there the following morning for pick up. Without getting political...there is no French language on the container,only English and Spanish...Canada would be a very insignificant market,,,😊

I have a number of vintage cars with stock standard transmissions,several are equipped with the overdrive option, (all are 1952 and older). I am hesitant to recommend the best transmission oil to use .While there may be better products on the market today,I use the same gear oil as what Plymouthy mentioned.... I might add that the price per gallon Plymouthy quoted sounds about right, I bought mine several years ago and it was a little less expensive🙂
