Have had tranny cooler for over a year...
I am still torn as to whether or not to install. Will it really make a difference on a 96? My mechanic has said we should leave well enough alone.

Re: Have had tranny cooler for over a year...
I never saw the need to put a cooler in my 96. I got my car with 42,000 miles and in the 10 years I've had it, never saw transmission problems or heat.
And it gets warmer down here than where you are. Believe me, if I saw even the slightest need, it would be in there. OT has connected the SSM countless times and the tranny temps were always good. .

Most of the SVXi that come here have transmission temperatures right at or over 200°f! I have one customer that had transmission temps in the 240°f range. He came back later for a cooler in parallel with the stock in radiator cooler and the transmission temperatures went down to 176°. If we can control the temperatures on our two most expencive parts, the engine and transmission, then they should last alot longer.

Re: Have had tranny cooler for over a year...
Well said, Tom
I highly trust and respect his considerable expertise in this area. Had he ever seen the slightest indication that I needed to install a cooler, I would have installed one without question. What size is your cooler. You want adequate reduction in cooling, while allowing the torque converter to still lock up. .

Re: Have had tranny cooler for over a year...
On another hand Tony,
I just drove my son Nick's 96 4.44 SVX 1602 miles from Abilene Texas, to Wiley Ford West Virginia with no TQ lock up, and only third for high gear. 4000 RPM at about 60 MPH.(about 27 hours driving time) I/We ues BG Prouducts full synthetic ATF, Mobil1 10/30 in the engine with a L30165, and Mobil1 75/90 in the front and rear differentials. When his trans lost fourth gear , IN Abilene , all I did was to hook up the SSM, and (later when I thought of it) pump up the tires to 40/35.The transmission was at 198°f for 99% of the trip, with a couple of 207°f spikes when I had to go faster to not get run over. Only once did I see 208°f, for a minute. Back down, crank the heater to cook me. The 4.44 in his SVX is from a 1996 Subaru Outback, and I BELIEVE that he has no external transmission cooler. I DO KNOW that he does not have an external transmission filter. The trip just reminds me that we should ALL have synthentics, just in case. It never hurts to have an edge, or an out!

Re: Have had tranny cooler for over a year...
As you can see in my signature, I have synthetics all around now. The reason I am asking about the cooler is that I need an oil change soon and I am also due for the next drain and refill on the ATF. If I were to install the cooler, this might be a good time to do it as I won't be doing another ATF drain and refill soon.

Re: Have had tranny cooler for over a year...
I know and respect your knowledge of lubricants.
It far excedes mine.  But unless you know what YOUR cars' actual working temperatures are, (or pressures are) then you do not really know whether you need the extra cooler or not. The guy with the 240° temps, this was after we had changed to synthetics!  If you are going to Reading we can run the SSM ang get an actual number.

Re: Have had tranny cooler for over a year...
@ SVX files. How on earth do you manage to stay awake for 27 hours at 60 mph? Hats off to you.
Just to throw my amateur opinion in here, in the UK we don't experience high temperatures that often. My SVX, left in 'D' at WOT changes gear with uncanny smoothness. It makes me suspicious because there must be some heavy clutch slipping involved to enable this IMO. My XJ8 also changes as smoothly but has more gears and lower final drive ratio and therefore seems happy. In my bike experience clutch temperature causes swelling and the increase of free play at the lever, therefore it drags. Presumably, when an SVX high gear clutch suffers the same fate the operating system can't accommodate this expansion and compounds the problem, leading to failure. I reckon that any sort of cooler won't stop this happening, or rather won't cool it fast enough. Driving the old girl in 3 till 80mph has worked for me so far, and the added engine braking inspires confidence. Plus the motor usually isn't far off it's magical 4500rpm+ transformation which is handy for overtaking/fun.

Left on Sunday around 3:00 PM Texas time. Spent a short night is the nastiest hotel that I have ever been in in Arkansas. Stopped out of my way on Monday night at my brother Marks place in Cincinatti Ohio. And got home dead tired on Tuesday. Yea, I'm old.
