TerranoNZ Posted September 5, 2009 Share Posted September 5, 2009 As most people know my trans blew up a while back and I've been rebuilding it myself. After getting the torque converter rebuilt (That was what blew) I ordered 2 shift kits and a few remaining bits I needed. I can't offer a complete how to, but with the FSM it's pretty easy to pull the trans apart. This is more so people can see what's involved before taking the job on. Should you do it? Well I've rebuilt a few engines in my time, I've a pretty good mechanical understanding. I've got the FSM to work from, without this I wouldn't of started it This is what you get in the kit + instructions. *The 0.041 drill bit arrived broken, but was not a big deal as you only need that for the "Heavy duty" option. Tools you will need: Basic tools, socket set, spanners, cir clip pliers that sort of thing. Vernier calipers Power drill Parts wash Step 1: Cross drilling through gallery As per instructions, remove the pressure regulator valve. Some of the valves were hard to remove. I had a magnet that was too big to fit inside. But with a cunning plan Using a pin as an extension I was able to get the steel valves out easy. Place the body protector in place. Use the 0.062 drill bit to drill through the body wall. Clean out the body with parts wash, make sure to debur the hole on the other side. Step 2: Pressure valve spring Measure the spring, if in spec as mine is add little blue spring. (Blue) Step 3: Sequence & Relay valve Remove the valves and replace separator plugs and pins. (Red) Be sure when reinstalling that the springs are seated on the clips correctly. Link to comment Share on other sites More sharing options...
TerranoNZ Posted September 6, 2009 Author Share Posted September 6, 2009 Step 4: Pressure modifier Remove and inspect for cracks. (Yellow) Don't really know why that's part of a shift kit Step 5: Modifier accumulator Remove and inspect for cracks. Step 6: Drilling separator plate Let the fun begin Drill as per instructions either Regular duty or heavy duty. I went with Regular as this is my DD and I read that someone went heavy and thinks it shifts too hard. Debur all holes and clean swarf. Step 7: Put the valve body back together As in FSM Step 8: Replace accumulator seals As pic these are Teflon seals not O-rings, hence the split in them. 2-3 &1-2 Accumulator only (4 seals) They are a PITA to install. Use petroleum jelly to hold them in and quickly push them in, but don't push too hard. Step 9: Replace accumulator spring New spring is red colour. Very hard Step 10: Replace Servo cover gasket Pretty straight forward, Torque bolts to 11.5Nm (100 In/lbs) Step 11: Orifice plug My case doesn't have the plug or ball in question, so I'm done here. Step 12: Replace rings on stator support shaft 2 large and 2 small.....Easy, just careful of the Vaseline DONE Now cross your fingers it works Link to comment Share on other sites More sharing options...

adamzan Posted December 23, 2009 Share Posted December 23, 2009 Tex, how has it been running? Also I want to get a crapped out wd21 auto and fool around with it and learn. And possibly install one of these kits... Link to comment Share on other sites More sharing options...
TerranoNZ Posted February 12, 2010 Author Share Posted February 12, 2010 My bad Adam... I missed your post, better late than never Shifts really nice, Hard shifting seams faster and gentle shifting is sometimes unnoticeable. I wish I could post a vid, but it's really one of those things you need to feel. That's a damn good idea Link to comment Share on other sites More sharing options...
madhornet Posted September 14, 2010 Share Posted September 14, 2010 can this be done in the truck Link to comment Share on other sites More sharing options...
TerranoNZ Posted September 19, 2010 Author Share Posted September 19, 2010 Only steps 11 & 12 have to be done when the trans is out. I really think you won't notice the difference though Link to comment Share on other sites More sharing options...
