I have a spare 4.0 and TF999 lying around. I am building them both to swap out my wore out old motor and trans.
These torque flights are really easy to work with. No real specialty tools needed, a pick set and some good snap ring pliers. I took the pan off and pretty stoked by what I found. Turns out this trans has an electronic solenoid for a lock up converter. Unfortunately my 91 doesn't have the electrical connection for a lock up converter off the pcm. BUT, this is a simple 1 wire solenoid that is internally grounded. So I am going to hook a switch on the dash with a 12V+ and wallah! have a "4th gear" when I am on the highway.
This is the part I was interested about... Will some of you guys who have rebuilt a transmission take a look at these bands and clutch plates. They look like they are in good condition to me. I actually believe this thing might have been recently rebuilt due to the fact that all of the gaskets looked new and oil seals. I figure while I'm in there I will still replace everything, but I just wanted some opinions on the condition of these clutches.
I am going to start modifying the valve body for the Transgo shift kit.
