do you think it helping it cool

[mr gtx]

i always remove the cover plate on the tranny and put on a screen. do you think this helps a lot in keeping the torque converter and tranny cooler ?

It can’t hurt. I leave them off, but I’m on clean pavement, no gravel.

Install a trans temp gauge, drive it around and get a baseline. Now put the solid cover back on and do the same type of driving. Then you can tell us how it works.

On the internet, I have read that the torque converter cover is too thin to hold in significant heat. I have a gravel driveway so mine stays installed.
My experience is that good non-kinked trans oil lines to the radiator and radiator that has been flushed by a shop usually gives adequate cooling.
Otherwise, you can set up a trans oil cooler in front of the radiator.

deep pan can also help

I always wiped a lot of crap off of those covers. That told me that they are worth it.

IMHO, any cooling would be minimal. Keeping the dust and crap out would take priority over it easily.

It seems to me that you have dirt and dust getting into the convertor area, courtesy of the open bellhousing area that's now a undercar scoop. While it might not hurt it, it seems to me that keeping that dirt and dust from finding its way to the front seal of the trans might be the best to keep the seal in good shape.

I could be totally wrong here, but I've always run the shield and as @commando1 sez...

WISE words! Accumulated dirt and gravel will sure as **** CAUSE overheating beyond the paltry convective cooling one might initially get from exposing the TC to dirty air. I explain to my little urchins that Clean Machine = Cool Machine.

You stated it first, so I needn't repeat it. Bravo

The biggest heat generator in a tranny is the torque converter. Heat generation occurs as a result of designed slippage inside the converter. The biggest slippage occurs when you come to a stop and idle the car in gear such as waiting at a light. In heavy traffic the best thing to do is put it in neutral while waiting. A cooler also helps.
I would leave the cover on for the reasons mentioned above.

The early PowerFlite transmissions had vented bell housings. a small oblong, screened vent at the top and a larger square, screened vent low on the passenger side facing the side. That is, if my memory of 50+ years is in any way accurate. By the time the Torque Flight trans came along the vents were history. It seems the engineers found the vents didn't work well or caused more trouble than benefit. Therefore, I agree with the wisdom offered above- Cover on! Lindsay

Thosea early to mid 50’s cars didn’t have a trans cooler, so that was the only means of cooling. Bad idea With no fluid cooler. The converter had fins to move the air like a fan.

the factory doesn’t know how the car would be driven, deep snow, farm use, country roads, kids going cross country, etc. think dukes of hazard. In these situations that big open scoop under the car would be a problem.

At idle it is not making heat. If so every auto trans car in afternoon traffic jams would be overheating. Converter makes heat when you put power through it.

I have a trans temp gauge on my pickup, plumbed into the cooler lines. It is amazing how much heat it makes towing up a mountain pass.

And it cools off very quickly at the top of the pass going to flat or downhill is the same. Like in 2 minutes it’s back to where it was before the hill climb. The trans temp gauge doesn’t rise at all sitting in traffic on a hot day, it cools off from the driving it was just doing to reach the traffic jam. All because it’s not doing any work.

Now putting it in neutral is good because it raises the rpm, which speeds up the fan and water pump helping the cooling. Also speeds up the engine oil pump whigh pumps more oil, and more oil through the engine helps cooling also. Watch you oil pressure gauge on a hot engine idling in gear and then neutral.

but this doesn’t mean you need a high volume oil pump and 80-100 oil psi, that’s overkill.

thanks for all the input. i did put a screen on to keep the stones and debris out so the worst thing will be the dust. am running the 11" factory super bee - road runner converter not sure how much extra heat it produces over the stock 12". it does have the deep tranny pan, high efficiency radiator and with a little help with the screen I hope it will be alright.

Having just replaced my B & M tranny cooler upline from the radiator cooler, I note that now engine coolant stays just above 180 F. That little B & M dumps a LOT of heat BEFORE the tranny fluid comes in thermal contact with the engine coolant, and on the '68 bumper, the front license plate screws mount the cooler perfectly, with a nice little vent immediately in front of it to catch the breeze coming in.

I think my ride is now fully ready for AZ summer heat in traffic! I also swapped my second 2524984 radiator, which I had rodded and sealed a couple months ago after buying it and the factory Mopar shroud that went with it. This is an awesome radiator, meant for AC, high altitude, towing and all the aforementioned together. I suspect my original one is due for a new core, so when we get a grand to burn, the tanks will go to US Radiator, as I like them. I plan to have them add a 4th row at high efficiency spacing. But we're VERY happy with this find I bought in Florida.
