Hey all,
so it's become obvious to me that I need a transmission cooler set up. With 330 hp and using a 901 box, it's going to start destroying gears (already did this past weekend at Road Atlanta). So, what is everyone using and how are they set up? What pump & cooler? are you using a resevior/tank? Where is the cooler mounted? and where are you getting the oil in and out of the trans? As you can see, I'm a complete newbie about this, need to educate and do as quickly as possible...I'm running out of transmissions! Pictures would be wonderful... thanks!! |

Bob,
Thanks for the reply. I am a big fan of using empirical evidence, so if it has been working for Lou, then kudos to him for trying something new and making it work. I think I still would not recommend that everyone do this unless they know what they are doing. I have seen "how to" instructions on these transmissions in which people have used RTV (and other sealants) in place of the paper and I think that was done out of ignorance and not via a proven new method. My concern (especially for amateur rebuilders) is that if you have to use multiple paper seals to set pinion depth and you also apply a sealant to each layer that it could adding up. That the thicker the sealant the less likely the assembly clamping force is going to squish all of the extra out (seven layer burrito!) And lets face it, the main reason any type of sealant is going to add value here is if you have a buggered up sealing surfaces. Maybe someday I will dry assemble a case, measure depth, then do the same thing, but with the addition of some type of sealant to see how the depth changes. I would be shocked if it doesn't, but the pinion depth spec does allow for some leeway (you can't expect to achieve optimal depth with just the metal and paper shims), so I can see if you are on the right side of optimal, that some extra sealant might not hurt. But if you are on the wrong side, some extra sealant might actually not help. Regardless, I love this thread as it is interesting to see what everyone has tried from a cooling perspective and what works and doesn't.
