My truck has been a work in progress since the day I got it back in 2000. Anyways, you can read the progress here from then until now here: http://dyogim.blogspot.com
In more recent updates, I'm currently working on doing away with all the push button/ADD/electronic 4WD set-up. Beginning of 09 I started having issues with my 4LO. 4HI worked but, for some reason everytime I pushed the button for 4LO, the indicator blinks. Prior to the 08/09 winter season, it worked with no issues. So, I figure bad actuator at the tcase.
Mid summer, I went wheelin' and without 4LO, 4HI was working the drivetrain too much to the put where my trans temp light came on. I figured due to the slow movement and high rpm's things got too hot. After that trip, I installed an e-fan directly to the tranny cooler.
Instead of trying to fix the actuator on the tcase, my plans are to swap out the auto tcase for a manual tcase. The tcase I'm getting is from a 2.7 taco/runner 00-03. Which is 21 spline. The tundra is 23. Supposedly, the tcase found on the V6's of the same model/year use the same casing as the 2.7. The only difference between the two, is the outshaft length and spline count. If the tcase found on the tundra also has the same casing, I'll be removing the output out of mine and swapping it into the manual tcase.
Once the tcase arrives, I'll start the teardown and comparison. I'll try and take as much pics as I can and keep this thread updated....
