Torque Converter/Tranny Question Ok, I got a ST-3500 about 1 1/2 Weeks ago from a GP...now there is a letter in there that says i need a tranny cooler...is this for real? Do i need a tranny cooler or can I get away without it?
Re: Torque Converter/Tranny Question You can get away without it...but only if you want to shorten the life of your tranny. A cooler serves two purposes. One is to cool the tranny. Heat is the #1 cause for premature trans failure and small 9" converters like your Super Thruster generate a lot more heat than the stock converter.
Increased fluid capacity is another good reason to run a cooler. When you switched from a 300mm converter to a 245mm converter, you lost at least one quart of trans fluid (because of the smaller physical size of the converter). A cooler will bring some of that back...as will a deeper pan.
If you were running a larger Yank 3000 or a Super Yank 3500, you may be able to get by without one, but with the ST3500, I would highly recommend one.

Re: Torque Converter/Tranny Question Buy a plate type cooler, no less than 16,000 GVW (cold climate) or more than 24,000 GWV (hot climate). They are available for about $50 from several sponsors and take 15 minutes (experienced mechanic) to an hour (rookie) to intsall.

Re: Torque Converter/Tranny Question I consider it an absolute must in many cases and some damn cheap insurance in all cases. <img src="gr_images/icons/cool.gif" border="0"> No need to skimp on this one.

The B&M unit (24K GVW) I ordered from Thunder came with everything needed to install the cooler.
Wel, except for the little bit of trans oil you will need after the install...

Re: Torque Converter/Tranny Question You can try the Northern Auto Parts site at http://www.northernautoparts.com I know this is a lot to punch in, but this is the cheapest site for the Hayden Trans Coolers, which I have resently installed. Mine is a 26,0000 GVW cooler as I have stated on a few different post, I do not beleive in the too cool rule. BTW, I was riding around all day cruzin at 135 degs, shifting just fine. <img src="gr_stretch.gif" border="0">
