No, I will probably use a switch.

Jon@TRE told me to keep it on all the time because the tranny will be overfilled if it wasn't turned on. I need to talk to him about it a little bit more.

 

Hm.. that does sound like a PITA. Maybe put a bracket (3 or 4 posts) on the radiator unit so you can attach or remove a simple sheet metal shield with quick release clips? (like RC cars use for lexan bodies but metal). You could weld 3 3/16" flanged posts onto the outside edges of the radiator block and bingo. Or maybe a shroud that slides around the radiator from the side and clips in place. Only take it off for track days... The extra fluid volume would help to naturally cool for normal driving.

It would shield the airflow on really cold days so the pump can run constantly to prevent the tranny box from flooding. I'd hate to run the system on a -10° winter day and have it sludge up because the oil is so overcooled. Your tranny would essentially never warm up.

 

I think I'll be changing mine after the next event...

 

I don't have to worry about the -10F days here in California except for the odd really cold nights in Tahoe but I don't take the EVO to Tahoe anyway.

I don't think the extra oil will cool the tranny more, i think it actually makes it worse, which is why Jon told me to run the cooler and pump all the time. Again, I need to talk to him a bit more about it.

 

I would urge you to do it before your next event.

 

ditto, i emailed tim, because he's used the car, very similar to what i have.

You haven't run enough events, to be seriously concerned, but i'd still swap it, just to get all the initial particles out.

 

I only have 4k miles... Still think I should change it?

 

yeah dude, if nothing else, to be safe.

I waited WAY too long, my stuff was nasty, but as razor pointed out, no telling what of that was initial wear. the tranny is easy. the rear diff is easy, the transfer case would be easiest done with the downpipe off.

I'll be swapping every 3-5 events now, and seeing what it looks like, i'm shocked i still have a tranny.

 

Instead you bum rides off me to Tahoe in my Evo.

 

The first time I did the the tranny, tc and rear diff. The fluid from the rear diff had a lot of metal particles in it .... looked like metal sludge towards the end of the drain. I'm going to do it again next week, find out what it looks like ... I'm sure it will be better as the tranny has had a chance to break in and wear smoothly. Also I would recommend everyone use only the factory fluid in all 3 compartments ...

 

I've taken mine to the dragstip a few times and was planning on autocrossing next month. But after reading what has been happening I'm having douts.

 

YOu don't autocross in 4th, so it's no worry. I have done 200+ drag runs, 20+ autocrosses, and 500 miles of track time before 4th went out. I also drive really hard and am pretty fast, so it wasn't a big surprise this happened to me.

 

I'll be changing mine next week. Yea i don't think autocross is an issue, I never got out of first gear the last 2 events and still took 2nd fastest of the day in all classes. The road course abuse is what concerns me. Almost all of it is in 4th dropping to 3rd in corners and back to 4th. So yea, it's definately time for me. I'm kinda scared at what it's gonna look like...

Is there a write-up with some pics somewhere to make it easier? Or I'll just figure it out, nevermind

 

tim, if you have any questions, just shoot me a call, it's not hard at all.

 

damn, i normally get 175-225 miles on track per event (depending on venue)
