Tranny temp ?
So, what temperature is considered too high for an A4?? Just curious so I know what to look out for. I was under the impression GM put a cooler in the cars, but it seems like everyone with a set of gears & t/c are putting them in.
Where & what price is good for an aftermarket tranny cooler.

Anything above 240 would be too high. A lot of forum vendors sell them . The average price is around $50. Have you looked into the transgo shift kit ( $109.99 ) it comes with one . So you get better shifts & a cooler tranny. Win/Win.

Whoa! Let's backup the train here just a minute...... The $109.99 for the transgo shift kit INCLUDES a tranny cooler???
Gee, I might just have to get one of these even before I convert my t/c & gears. Please confirm this, thanks!
Has anyone tried to do the install for themselves??

Re: Tranny temp ? (dads01dream)
Any prolonged tranny temps above 210 cause the fluid to break down & start to degrade...tranny damage will eventuly result. Short term temps up to 240 are OK, but not for more than 5 or so minutes at a time. This guidline is what we use in drag racing.
A tranny cooler should keep you below 190 at all times. Mine runs 168-174...and we run this car hard.
Get a tranny cooler for sure! I had not seen the transgo kit include a cooler before, but there may be one.

Re: Tranny temp ? (TLewis4095)
I am trying to remember where I read the same :confused: but I 'm pretty sure it was from a Forum Vendor. I just purchased one from ( LS1 Speed Inc. :thumbs: - Mike ) I went and checked it over there but no mention of items included in the kit. I am expecting the same within this week . :D I will tell you what I find inside if you will wait. Take Care. :seeya

Ok V-8...... I'll wait to hear what's in the box. Are U going to perform the install yourself? Another forum member recently did a writeup with many EXCELLENT pix on the process, sure it's involved - But it's not like actually rebuilding the tranny!!
Keep us posted.

Will do. No I won't be doing it myself my car is at the shop right now getting ready for major surgery ( Engine has been opened up + tranny ) so I figured I will install the shift kit at the same time . :seeya

Re: Tranny temp ? (KKu77)
I agree! If you're going to go with a higher stall TC you absolutely need to install an after market trans cooler to increawse your over all trans fulid cooling capacity. It would be very surprizing if the higher stall ratio TC didn't make your trans run hotter. This is due to the increased slippage which creates additional heat at lower rpm driving. You need to keep the trans fluid cool to avoid all kinds of trouble. I think most good trans shops will recommend a cooler along with the new TC.

Re: Tranny temp ? (dads01dream)
I consider a transcooler a must when you have a high stall converter. On the few occasions that I was driving in city traffic before I installed the cooler my temp would climb to 225 after about 20 minutes with my SY3500.
I’m using the B&M 70264 transcooler. It is a stacked plate design, which is supposed to be more efficient than the tube and fin coolers. Combined with Andy’s HD radiator, the transmission temps are usually lower than 185 when the converter is unlocked. On occasion during 90+ weather and hard, country road driving I’ve seen the temps go as high as 204. The 70264 is rated at 2400 GVW and while it does the job most of the time, bigger would be better.
It works fine at the drag strip but on a road course it is entirely inadequate as the temp rises to 235. I’m going to replace it with the new 70274, which is about twice as big (11x11x1½). Here is a little more info from the B&M site: http://www.bmracing.com/products/acc...perCooler.html
