Chase, I am working on the writeup for the Transgo DIY as we speak. I may have to do a tech elsewhere and link it. Crap, I also have to go back to work tomorrow. I better get back to it. I paid $65 for my E4OD-HD2-D kit off of ebay.

During my rebuild I installed everything in the E4OD-HD2-D kit except the spring that mods the line pressure modulator valve, I opted to change to .427 modulator that I had in there before. I also put in the on-off converter lock-up valve that converts operation from a pulse width modulated valve. Torque converter now locks up like it is shifting into another gear. If you have the pump out this is the way to go. No slipping into engagement by the torque converter clutch pack. There are also parts to increase regulated pressure of the pump and converter lock up pressure.

Great post and explanation Roland. I was trying to rep you but you are too recent. I am going to start a new thread here shortly as I cannot really work with this Photobucket setup to get the writeup going. Feel free to chime in and correct or add.

Folks, I will try to do the writeup, or something similar here tonight after I wrap up a few loose ends. Stupid rain. The video is good, but does not even cover the plate or the solenoid pack. I will check back. You really can do this yourself. BTW, my kit has the or at least some front pump mods. I did not do those.

The HD2 kit is very similar to the Tugger. Just doesn't include the parts to modify the front pump, which requires removal to do. I did all these mod while rebuilding/ upgrading the trans. There may be a few other parts included that won't be used unless you have the trans apart. Some mods to the valve bodies are model specific.

SK-E4OD Kit
I had the cheaper kit installed. At part throttle (normal driving) 1-2 shift is firmer, 2-3 is still too soft, 3-4 seems firmer. At agressive or WOT, all shift seems quicker and firmer. From what I was told, the cheap SK-E4OD kit contains all the parts to add a shift kit without removing the trans. Now, I don't know if they are the same parts or all of the parts (accessible without trans removal) that are in the HD-2 or Tugger kit.

Sounds like, overall, the Tugger kit is worth the extra cost if all the parts are installed. I have not had any problems with the HD2 kit, but I again have installed, and recommend to replace, all the parts in the kit. With the HD2 kit, you would only 'not' be doing the low/reverse valve mods (if the trans is still in the truck).

I got it all done this weekend (well most because I did not pull the tranny). Seems alot better in shifting not so lazy. I have not pulled with it yet, so time will still tell I guess. I followed the instructions for drilling the calibration plate for the diesel engines and was nervous it could to be to harsh, but it is not, could be a bit firmer. Maybe in the winter I will pull it down and drill the holes larger...The directions for myself could sure be better, for a person who has not done one before (but hey thats just me). It is not just a simple bolt on, but it can be done, be prepare to get oiley......lol

I guess some of you guys like *really* firm shifts, because I love mine the way it is. It's nice & short under "normal" throttle, and when you're really on it, it's pretty hard. I didn't want mine shifting like a race car. Although I wouldn't mind it, my wife & daughter probably wouldn't like it too much.
