F150 twin stick test drive

Описание: PLEASE READ THIS DESCRIPTION BEFORE ASKING QUESTIONS. This is simply a 4 speed transmission with an add on overdrive. Advance Adapters makes the overdrive. I make it look complicated in this video but does not have to be. I can use as few as 3 gears for normal day to day driving and never touch the small stick (overdrive). In the video I am shifting in and out of overdrive in every gear just to demonstrate the 8 possible gear ratios.

There is never a practical reason to use all 8 gears. When towing I do use overdrive in 3rd gear which is called gear splitting. Every once in a great while if towing up hill from a dead stop I will use overdrive in 2nd gear. I never use it in 1st gear, its just a waste of time.

The long stick is an old 4 speed granny from a mid eighties Ford truck. It is a Borg Warner T-19 with the 5.10 1st gear ratio gear set.
1st gear is called granny low because it is only used if needed, normal driving you start in 2nd gear with a granny 4 speed.

The add on Overdrive is made by Advance Adapters. www.advanceadapters.com

It bolts in front of the 4 speed, It bolts up to the bellhousing and the stock 4 speed bolts into the back of it, much like a transfer case bolts to the back of a transmission. It has its own separate shift lever and is totally independent of the 4 speed. It can be shifted at anytime , even in reverse. It can be shifted into Overdrive and left there at all times if desired. Or left in direct (I call it direct because it is a straight pass through, no gear reduction or gear changing at all).
It can be as simple or as complicated as I want it to be.
Normal day to day driving I start in 2nd gear, and without touching the short stick shift 3rd and then 4th. If I get above 55 mph then I simply shift the short stick into Overdrive. When slowing down I first shift out of Overdrive and then from that point drive it as a simple 4 speed.

FAQ:
Why the hell did you do this? Because I wanted to, I love driving a manual transmission. I used to drive semi trucks, did it for 12 years. Since I no longer drive trucks this is the next best way to get my gear jamming fix.

Is this factory? No
I removed the stock 5 speed transmission and installed this Overdrive with an older 4 speed transmission.

Can I do this to my truck? Maybe.
They make these units to work with Ford and Chevy 4 speed transmissions. They also make one for a Toyota to adapt a chevy engine to a Land Cruiser 4 speed transmission. That is it, only 4 speed transmissions for Ford, Chevy, and certain Land Cruisers.
THEY WILL NOT WORK WITH NEWER 5 OR 6 SPEED TRANSMISSIONS.

Why the f*&k would you do this to an F150?
It may seem like overkill but it really is not. This Overdrive was first made back in the 70's by a now defunct company, at some point Advance Adapters bought the rights and the tooling and started making these units. If you had or have an older truck with a granny 4 speed this unit was a wonderful upgrade. It's main function was to give you an overdrive gear. It just so happens that you can also use it as a gear splitter.

How does splitting gears work?
It boils down to simple math. My 2nd gear ratio is 3.03 to 1
My third gear ratio is 1.78 to 1. However if I use my Overdrive which has a ratio of .79 to 1 in 2nd gear it gives me a gear halfway between 2nd and 3rd. I have split the gear in half, hence the name splitting gears. It works like this... 2nd gear 3.03 to 1 multiply by Overdrive ratio of .79 to one. 3.03 x .79 = 2.39
that ratio is between 2nd (3.03) and 3rd(1.78) so 2nd Over is a gear in between 2nd and 3rd.

Can I use this with a 4wd truck? Yes, if that truck has a Chevy, Ford or Toyota 4 speed transmission. Since it bolts in front of the transmission it can be used even in 4wd. The transmission and transfer case simply get pushed back apx 6 inches. The front driveshaft would have to be lengthened 6 inches and the rear driveshaft shortened 6 inches.
With a floor shift transfer case you would have a triple stick truck. Now that would be cool! You would be even cooler than me!!
If you had a twin stick transfer case then you would have 4 sticks!!
If you had a Toyota land cruiser with a Chevy engine, stock 4 speed with Toyota transfer case and also had a Marlin Crawler with a twin stick transfer case.... 5 STICKS!!!!! Where the hell would you fit 5 sticks?? It would look like a back hoe , or a forklift.. Lol
