i hurt my trans in my GTP a few years back, and to buy myself some time to save up i pulled my blower belt and ran it for a few months like that with no ill effects. i actually took it to the track once and it ran mid 15' like that. belt on it went high 13's.

Just did this install today, before the install in 60 degree temps driving around town I saw a high temp of 212 and normally around 210 or so which I thought was kind of high.

So I installed the Hayden kit just a little bit ago, I went for a drive and and the temp stays right at 192 degrees, unless I get on it for a bit then I goes to around 197 and stays there.

Are those the results I should be expecting? I got the same kit as in 7psi write. I thought the temps should be lower.

Check the fluid level. Wipe the dipstick with a white napkin. If the fluid residue on napkin is brownish in color then do a fluid change. To heck with service intervals, that is the best way to check the 'health' of the tranny fluid.

Unless its a very large (45,000+ BTU) cooler you should be using it conjunction with the factory cooler. Most Trans coolers are auxiliary and cannot dissipate enough heat by themselves and you are not gaining anything at that point.

second day owning a gxp now traded in my GTP...love the car first thing i noticed was the dic info displaying my trans temps during grandpa driving. i went to orielly and bought the biggest cooler they had IIRC the one for RV's and installed but not according to the writeups i mounted mine inline but in the bumper instead. i realize the optimal location for the cooler itself but it was to much **** to mess around with so after taking a drive in the arizona hot weather and now onstead of 200+ degrres my temps will not rise more than 167 not to mention mounting in the bumper is a whole lot easier pics are below... question for GXP guys....is there a way to disable thos pointless drl lights? i tried unplugging them but it gave me the idiot message on my DIC...

On the turn signal stalk are the lights. I believe its auto, parking, and manual lights. When in auto rotate it toward you and I think you can turn the lights on/off.

Do they not make coolers that you don't have to cut the lines and tap into them?

91parkave, What are the dimensions on that cooler?

It helps the longevity I your trans, they run a little hot because the TCC material that saturates the fluid - follow service intervals for severe duty to change fluid.

The easiest way to beef up the trans is to add the Transgo shift kit or have it tuned to adjust shift pressures.

Good luck

Has anyone had any issues with the coolers in the mid-west region (or any other cold regions) with extreme winter conditions? Also, should i continue to go with traditional trans fluids from shop or royal purple or something. I'm located in Kenosha, Wisconsin. Thanks
