Message: [QUOTE="early99powerstroke, post: 622788, member: 1262"] my transmission overhaul took a long time. But to save costs tear down your transmission and send off the stock shafts and I'd also recommend the flex plate too. I sent my stuff to a company called "300 below" and their costs were very reasonable. also be sure to pull the plug on the forward drum and tap the hole to accept a set screw to sit flush (the plug has a tendency to back out under high line pressure and main pressure). you can get steel planetarys out of a 4R100 and you can have these cryo frozen also if you want to beef these up. I enjoyed building the transmission myself it was extremely stressful but now I have the whole rebuild process memorized and I can say I was able to do it myself. Remember the secret to a transmission to hold alot of power isn't a bunch of thin clutches and steels but quite the opposite. If the line pressure can be applied accordingly and if the main pressure and clutch clearance is tight enough the stock clutches will hold more power and stand up to the heat even better then any after market clutch on the market. If the clutch doesn't get a chance to slip then it won't build excessive heat which means the clutch wont break down. Good luck on your build. [/QUOTE]
