What size tranny cooler do i need with a stall from 3500 to 3800 and its driven 250 miles a week. that includes stop and go and road trips. ohh and b/c i live in houston where it gets really hot in the summer should i get a big one? Its going to be a TCS TC, and i was thinkin B&M tranny cooler, are those pretty good?

The size of the trans cooler, on any street driven car, can never be too big (the bigger, the better). <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> The B&M race coolers are pretty good, but have a flaw in the design. The race coolers are designed like a radiator with fluid passing through fins instead a tube. Clutch dust and small metal shavings (that are common in all trannies) will stop flow through these fins, thus burning up the tranny. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> Stay with a cooler with the tube design. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Which one has a tube?? and i heard that it can hurt if its too big b/c its too cold. something like the TC doesnt opperate correctly <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

The tranny coolers that we and other people sell have the tube. Take a look at the coolers on this page. http://www.tciauto.com/cooling.htm

The computer makes the decision to lock-up the TC based on engine oil temp and tranny oil temp. I think you could adjust these settings by LS1 edit? When the 3800 TC is slipping, it is putting more heat into the tranny over the stock TC. So, I do not think that the cooler will cause a problem with lock-up.

Ragtop 99,

I recommend the tranny temperature to be at least 140-150. This allows for the fluid to fully expand and all the clutches, steels, etc. to get in the desired temp range for maximum performance. Your tranny should last a long time considering the temperature range it operates in. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Thanks for the input on the LS1 edit; I was not sure on the comment. I have a lot to learn about LS1 edit. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" />

Thanks for the info guys. ohh and Ragtop, where did u buy cooler from?

Drew

 

Kevin:

Thanks. Most of the time the fluid warms up pretty fast with a 4200 stall.

Z-rated:

I bought mine locally, but several of our sponsors carry coolers.

 

Drew check <a href="http://www.thunderracing.com/index.cfm?fuseaction=subcategory&subcategoryid=108 1" target="_blank">Thunder Racing. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> </a> I have the 24,000gvw B&M and it works great. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

I use a plate type cooler. The plate type coolers like a B&M Supercooler are generally more efficent for the space they use. Also for those of us who live in colder climates, the plate type coolers flow less when cold thus allowing the tranny warm up sooner and allow lock-up sooner. As the fluid heats up, the cooler flows more and increases cooling.

I would suggest at least 16k (only that small when combined with a 160 T-Stat and fan settings) and a 19K is better. For road race, I'd get atleast a 24K.

Kevin:

Do you have a minimum tranny fluid temp that you recommend before flogging an A4? I try to wait until the fluid is up to a minimum of 100* F. Normal operating temp for me is 160 - 180 depending on weather, speed and amount of flogging.

 

Josh i was already looking at that one from Thunder.... Thanks man!

ive got a tci3500 waiting to go in and my cooler is a B&M 24k gvw. like he said, cant go too big with it.
