About 3 months ago I finished installing a probuilt automatic and edge convertor 2600 stall. I also had 3:73 gears put in at the same time. I installed a transmission cooler and plumbed it in after the radiator cooler and then back to the transmission.
I don't have a gauge or my deep pan on it yet.
During the winter/spring the engine temps were good. Now it's summer and 110 degrees and I'm overheating everywhere except for on the freeway. I'be been checking everything in the cooling system with no positive results so I'm starting to grasp at straws.
Thanks

Im not sure if your car has electric or mechanical fan . But in either case check that the electrical ones work if present and if mechanical you have a thermal clutch on the fan as the car gets hotter the fan should move more air if when the car is hot you rev the engine and the fan moves little air thats probebly the issue , It should get rather loud when its hot from moving air.

Yeah, it is possible that the new trans is making more heat than the old one and heat saturating your coolant system. Check your fans first... and also your air dam.... if they are in good working order you could try putting the trans cooler before the radiator. If that doesn't work you may be looking at a new radiator or a larger fan set up.

When installing a converter with a higher than stock stall, you need to install an external oil cooler. The bigger, the better. In the side of the rad is a tranny oil cooler. It helps bring the hot tranny oil down to the cooling system's operating temperature. If the higher stall converter creates too much heat, which they all do, the efficiency of the rad may not be enough to remove all the extra heat and the coolant temp can go up.

It's always best to install the external cooler so that the tranny oil goes through the cooler first then to the rad cooler. It will bring the oil temp down. If it doesn't bring it down low enough, the rad cooler will bring the colder oil down even more. If it brings it down too much, the rad cooler will bring it back up to a proper temperature. Tranny oil should be running around the same temperature as a normal cooling system. Tranny oil can easily reach 250+F so it needs to be cooled.

The other option is to install a more efficient rad.

The engine fan(s) only provide air flow across the rad for low speeds. At highway speeds, there should be enough air flow across the rad to provide enough cooling. Having a fan shroud increases the efficiency of the air flow. The air dam under the car helps direct more air to the rad since there isn't a clear opening on the front of a third gen.

You can also mount a small thermostatically controlled fan directly on the tranny cooler.

I'd reroute the tranny cooler first so it cools the oil before going into the rad cooler.

when routing the trans oil to go thru the external cooler first? ....what is the routing of the lines? WIth the stock routing there is trans lines going to the bottom of the RAD and there is one going to the top.....which is out and in?

The way I have it setup now is....top line disconnected from the RAD and going to the top of the TRANS COOLER and then coming out from the bottom of the trans cooler and going back to the top connection on the RAD?

I have an external cooler and want to make sure that it is going thru the ex cooler first. I have a better than stock trans and a high 3400 stall and getting extreme heating in my trans according to the trans temp gauge and want to bring the temp down as best I can.

Transmission fluid flows in to the bottom port of the rad, and out from the top.

lol..so Ive got my routing all screwed up!!!!........no wonder Im getting trans over heating.


hold on Im comfusing myself.....how should I run it? one of the fittings needs to be pluged on the rad?

bottom line on rad to top line on cooler and then bottom line on cooler to bottom line on rad?
thats sounds right..to get the trans fluid to go thru thr cooler first and then back into the rad? and then it flows out from the top line back to the transmission

Fluid routes through your radiator first, then your cooler. The line into the bottom of your radiator is the from trans line, it is also the bottom fitting on the trans. The top out of the radiator goes to your cooler. Your cooler then routes back to the return hardline which is the top fitting on the transmission.

If you got the money and a spot in your gage pod, just get a tranny temp gage I would be worried about burning up your tranny while you're at it too.

MAKE sure you get a good one...STAY AWAY from any of the ones they have at AZ or Advance..they are junk and not enough GVW ratings...I had one from AD and thought it was good but it turned out that the problem I was having was from my small *** cooler...

I got this one and its BIG and has a GVW of 25000..and it bought my temp down ALOT!..PLUS it WAY cheaper than anything they have at the local stores..I only paid $39.95 shipped and had it in 2 days...its just as good or better than the B&M's but alot cheaper in prices ...atleast where I got mine

Here's some pictures of the one I got and also compared to the best one they had at the local chains.

PRETTY!!! I WANT ONE!!! ... No.. make that TWO!!

I live in Palmdale Ca (high desert) and I see a dramatic difference in engine temp once ambient (air) temp starts to rise. With a 180* thermostat, 180* fan switch and an external trans cooler (stock converter), the car stays at 170* indicated on the dash guage during Fall, Winter & Spring. But when summer comes, if I sit at a light or run the A/C in traffic, engine temp goes right to 220*. On the freeway I can run A/C and stay at 170*. My car does not like HOT weather. Your high stall converter no doubt adds some heat, but I think the summer weather (it's been 100+ degrees here for 2 weeks )
is taking it's toll. I have learned not to expect nice cool engine temps during summer. But, I haven't tried Water Wetter, or had the radiator checked (58K miles). I also have robbed some air from the radiator by converting the scoops behind the foglights to ram air ducts.
Bottom line, don't expect to see optimum engine or trans temps in the weather we're having in So Cal this summer, and, be "cool" to your new trans.
Let's hear everybody's tips on how to keep engine / transmission temps down.

ditto to that brotha!!!....I couldnt have put it better myself! I suffer from the exact same thing!..summer time shucks for the car...it hates it!

Burnout91, if you change your coolant mix to 30% anti-freeze and 70% distilled water with 1 bottle of water wetter, you should see your temps come down 3-8 degrees, probably 3 in your area. It`s not much but it does help.

Thanx for the tip!
