I finally rolled my truck out of the shop at 2AM this morning after a weekend of work. I had to be back here at 6:30AM for work, but hey sleeps overrated right? I installed a Dunrite converters single disk and valve body with some internal mods to increase line pressures and lubrication. A little machining on the planetaries here, machining intermediate shaft there, extra springs here. All in all it wasn't too difficult, just time consuming casue I wanted it to be perfect. The results are awsome. The truck shifts firmer without being harsh, holds lockup (via the installed switch) and has no slippage. Bottom line diffrent truck completely. Tony Garcin, the owner of dunrite and a drag racing guy from the 60's knows a lot about these things, and taught me a lot in the process of this job. He also said he would warrenty this for 5 years up to 450hp and 20,000lbs towing. I intend to stay below this level with a goal of around 350hp and so I will be very happy with this setup I'm sure.
Here are the results of the work, numbers wise anyway. My truck is stock for now, been waiting for the tranny upgrades to turn it up. I made a couple runs up a small hill behind the shop before and after and timed it.
0-70mph results.
Stock 24.6seconds
Now 21.2seconds
This is a pretty big improvement considering I didn't touch the engine. Now I can slide my fuel plate foward and install that gks kit, boost elbow and have fun :rockwoot:
For anyone considering auto tranny upgrades I'll highly recommend Tony, he supplies several of the big guys with their converters and will have you doing a lot more than just throwing parts at it, we actually fixed several design flaws in this tranny instead of just throwing stronger parts at it to try and live despite the flaws.
