The tranny cooler won't take any horsepower. Being a pressurized system and the tranny pump controlling it all you won't notice any difference. The tranny fluid should run cooler and this may allow for crisper shifts, but that would be all.

One of the best mods you can do IMO.

I don't see why a dealer would have any problem with a aftermarket tranny cooler. They only help the tranny to last longer.

Also, synthetic should improve the cooling factor since it sheds heat much easier. I would think that a bottle of lubegaurd would help as well by allowing less friction, which should decrease heat as well.

I don't think the dealer would have an issue with an _additional_ cooler, but I would be nervous about removing the stocker and replacing it.

I'm not saying I won't do it anyway, but if you had a problem with burned up clutches and bands in the trans and the dealer sees an aftermarket cooler, I'd bet most would gripe. I'm not saying they'd be right and I'm not saying that the aftermarket piece isn't better. Just wouldn't want to see someone get the shaft, that's all.

Hi Wes
Just read your post and I would have to agree with your advise. I also checked out your web page. Nice stangs and read about your desire for the Griggs suspension. I have a full Griggs suspension on both my mustang and t-bird.

Thanks BABolt for the compliments on the Mustangs.

I have the Ground Pounders tubular front end on my LX, but if I were to go road racing, I'd have to say the Griggs stuff is a bit better.

I'm debating on whether to make the Cobra more "race-prepped" for road courses. Not sure. It's mint with only 25k miles in the 4 years I've owned it...now that I have the L, it only will have 3.5-4k miles put on it a year. I have a number of local friends who road race and the fact is that is hard on the cars.

I do have a friend who I may go in with and build up a road-racer, though...and a complete Griggs front and rear would be at the top of the list. That stuff makes a night and day difference in handling/stability of the car, IMHO.

I assume you have nothing but good things to say about your two cars with the Griggs installed!

Just a question, I can see the desire to get additional cooling on the trans fluid, but why remove the old one at all, just plumb a new one in downstream from the 2 pass factory unit and consider it a pre-cooler. Makes perfect sense to me....

he he he,,,my dealer told me today my '00 would be in by 15 March,,,pant drool lust

I have not been to the track yet, my first trip will be next Tuesday. I have had my 2000 Lightning since 11/00 (new). However, my truck does this a lot on the street. I would say it has done it 30 or so times.... I do drive very hard, all the time, and I have a chip increasing the shift points to 5800RPM. Since it has happened so many times, and I can sometimes make it repeatable, I've had the ability to really watch and pay attention to what is happening. Does anyone else here read extremely high boost? I read high, about what I would consider 14-16psi. Since I'm only using the stock guage, and I know they can be very inaccurate, I don't know how accurate it is. However, the boost will only dump out when it shifts, and when the boost is very high. Temperature has been no apparent cause or relationship to it. It does, however, have to be FOT. It will do it a lot when shifting from 1st to 2nd, and also when downshifting either into 1st or 2nd. My truck has an awkward habit of downshifting from 3rd to 2nd when FOT the whole time. Right after it shifts to 3rd, it decides it wants to be in 2nd again so it will downshift immediately. In this case it will dump the boost 60% of the time. At the point which it dumps it, the boost is sky high. It will do this with and without the chip in it, although it has only dumped boost a couple of times without the chip.

As I know only of the blow-off that exists, I have attributed this to the blow-off valve and the apparent high boost. Possibly this information could help someone here who knows more about it to come up with something different. Also, the boost will remain low for a short period of time. I have experimented with pulling off the gas completely and driving "normal" without much apparent effect on the length of time before I have boost again. I do not need to stop the truck or let off for the boost to return. And by a short period of time I mean about 15-30 seconds. This certainly wouldn't be enough time to drastically change the temperature of the coolant, and I can immediately floor it with full boost.

Hope this sheds some more life on the topic.

#1, you're really lucky if your pulling 9psi max

#2, pull the boost cable off, you'll avoid all the problems that you mentioned.

#3, if this isn't enought info, please do a search there's tons of info on this subject.

 

Mav':

It sounds to me like you're hitting the rev limiter protection. If you bounce off the rev limiter, you'll trigger a boost dump protection fault. Whatever chip you're running probably has the rev limit set too close to the shift point. This almost has to be the case, based on your description.

Also, you better get your spare motor ordered up soon. You'll be needing it when yours blows to pieces. You're revving that poor thing WAY too high, and for no good reason (the 'Bolt makes crap power at that RPM). Please stop beating that poor puppy, and get another chip.

 

I agree with Silver, get a new chip !
I've had 2 chips in the past that had that same problem of not knowing wich gear it wanted to be in. I almost had some moron in a turbo volvo run me down because of it. That will never happen again.

Do a search before you buy a new chip.
