first....Jim....The J-mod is like what Rancherlee said.....This is an excellent Mod for your tranny (got to the link supplied in the thread above)...It makes your shifts firmer ( you have a choice of how firm) Basically It reduces the amount of slippage and friction in your tranny, along with making the shifts quicker and firmer.....While extending the life of your tranny.....Like I said, it was designed specifically for our cars by the guy who designed our Transmissions. Trust me...it's well worth it.
Spike the Tranny cooler is a external cooler that cools your transmission fluid. The transmission fluid in your car is currently being cooled by a tranny cooler that is currently in your radiator......However, as Jerry has stated, and as many people have experienced, these tranny's get very hot....Hotter than most other tranny's....the excessive heat in your tranny causes the breakdown of your fluid and thus resulting in an overheated transmission...that later needs a rebuild. By adding the tranny cooler and changing to Mercon V fluid...The Mercon V fluid can withstand more heat...and the tranny cooler will keep the fluid even cooler when it gets too hot, because it is mounted near the radiator where there is airflow.....so when your tranny is working and the fluid is getting hot...the fluid travels to your stock cooler and to the added external cooler, the added cooler cools the fluid as the air flows through it.
Cooler transmission fluid extends the life of the fluid and is better for the Tranny.
(Jerry's article goes much more into detail...I suggest reading it.)
I suggest getting a B&M tranny cooler from SummitRacing.com....They are the low pressure drop type(this means if the tranny fluid is cool enough...Then it will not travel through the external cooler to be cooled, instead it will only be cooled by the stock cooler) the reason for this is because you don't want fluid that's too cool either.
Hope this helps a little, but nobody explains it better than Jerry and his article
