Since the five speed costs the average SVX owner about $2500.00 and the six speed maybe $4000.00? Now go to your room and THINK about what you have said.

The size of the cooler should be determined by your transmission temperature. If you install too big of a cooler your trans will never have lock up. As to replacing the pan filter I personally am in favor of it for several reasons. 1)First of all they are like $30.00. 2)When the pan is removed you can check and remove the accumulated debris on the magnet. 3)By dropping the black cross flow tube you get about two more quarts out of the transmission. 4)When I replace transmissions I am REQUIRED by the transmission vendor to replace the filter on a used unit or there is no guaranty! 5)It couldn't hurt. Geez, another engineer. Husky, I have mentioned it in another thread! http://www.subaru-svx.net/forum/showthread.php?t=56310

Re: Transmission care
Sure, can't hurt as long as the person doing it owns a torque wrench and also invests in a new oe gasket so they aren't just creating leaks or a huge mess for the next go around. We all know how much we love taking a pan off someone has installed with that pink stuff.

Re: Transmission care
Well in that particular document you linked to and are sighting as a replacing the filter brought line pressure back instance he went from a long filter to a short filter so maybe his pan was dented--that causes a loss of line pressure. Anyway, a clogged filter is so contrary to everything I have seen I would have to suspect some sort of unaccounted for coincidence that was the true reason for a return of line pressure after a filter change if it did in fact happen.
I wired my air compressor into the 240 outlet for the the dryer the other day. I went to dry some clothes later the same day and the dryer didn't work. I figured I must have messed up a connection--too much of a coincidence for the dryer to break the same day. I checked the outlet poles with a multi-meter and they were all good but man it was just too much of a coincidence to accept the dryer broke at the same time--maybe a connection isn't tight enough so it has voltage but the dryer can't draw enough current. I took the outlet apart and retightened all the connections but the dryer still didn't work. To make a long story only medium long I did finally open up the dryer and find the switch that turns the dryer off when you open the door was bad. Not having a switch on hand and not caring if the dryer turns off I popped a crimp cap in place of the switch and my dyer works. Moral of the story is coincidences do happen and it will take more than one reported case of changing a filter restoring line pressure to convince me the screens clog. That's just me though. Others will of course make up their own minds. |

Yes I am sure they will.

Re: Transmission care
Tampering with the wiring is a long way away from changing the map that dictates what line pressure is in a particular gear. For one, tampering with the wiring effects line pressure at all times which according to your earlier statements must make you worry dreadfully about transfer clutch binding and what not. For two, when the line pressure is changed by tampering with the wiring the TCU does not know about it and can not take it into account in other routines like it can if the map is changed and a different solenoid a duty ratio is calculated. For three, tampering with the wiring defeats or partially defeats the signal/system which cushions the solenoid valve from fully seating and causing wear to the valve which will in the long run cause a loss of line pressure.

Doing a flat increase of 50psi to 150psi, a 300% increase, inhibits the throttle position from controlling the pressure at all, in 3rd or 4th. Quote:
Changing the specified variable number, that the program is looking-up, alters the result. The TCU does not know, that you have tampered with this specified variable, it just uses that number to produce the pressure. Quote:

Very little of what you just said is correct but I don't intend to get drawn into a harvey/trevor dynamic so I'm going to drop it now.

Re: Transmission care
With the greatest of respect Harvey, your method of tampering with the wiring will never produce a result comparable to a proper TCU remap.
The TCU uses a very complex algorithm to determine the optimum line pressure to suit a whole variety of driving conditions. It is not simply proportional to the throttle position. I am in full agreement with LAN here. The transmission is a relatively modern software-controlled system. The only correct way to recalibrate it is via remapping the TCU. As Trevor cannot be here to defend what you call his bull$hit, I'm going to restate my conclusion that neither you nor Trevor have a complete understanding of how this system works.

Great Scott! What the hell is a gigawatt!? I have to say though that really, while a lot of the things in this thread are debated, one thing is clear: a transmission cooler that replaces the stock one is a 100% good idea.
