Transmission I/D help

I need help, trying to identify this transmission. It is on 1984 F150<O</O
4x4, the identification plate numbers are as follow.RTSAJ-- KD29<O</O
<O</OE4TRJA-- 1089

The number on the transmission housing, E4TR700 followed by Ford.
Underneath that, it is a Clark
This is a four-speed manual transmission.
The other reason is the transmission gearing seems too high.
The gear ratio, I am running on a differential is 3:55.
And I am running 29 inch tires. But the truck has no
low-end torque or power. I hope you can help me solve this mystery
Thank you

Is this an OD, with first gear being fairly high?

"Clark" is in raised letters on the housing casting?

Several folks have mentioned Clark as source for these, but Tremec is mentioned also. When you look at the photos on the Kees site, it's clear it's taken from the toploader design but is a different casting.

I have the side mounted shifter version of this trans with 3.50's and nominal 31 inch tires. Not much low end and tough sledding with a load.

Are you thinking about putting a diffrent trans. in? I also found out that code-RTS is part of the T170F Series. Check out, www.motivegear.com/tech.
Thanks for your help. I will post any Info. that may help.
