Trans cooler issues On my build I am having fits trying to get the trans cooler lines together.
I have a 4L65e and a 2012 Camaro radiator all going in a 1955 Olds 88.
I have tried several adapters and have no issue adapting to the trans to remove the push-in flares, but the adapters don't work at the radiator due to the way that the cooler is inside the tank.
I am wondering if I can get away with by-passing the radiator cooler and just use a remote trans cooler?
Thanks!

I have no idea. I do not have the original lines (2006 GTO).
Would assume if there is temp sender it's on the Trans someplace?
I will look into that. I'm pretty sure if there is one, it's not on the lines or on the radiator.

I mean aftermarket with a temp gauge. You need to keep track and where you put the gauge will change how fast the temps read. Right out of the tranny will react quickest and in pan temps will react the slowest. On one vehicle I had one in the pan and one coming right out of the tranny and it would take quite a while for the pan temp to climb.

I will look to add a temp gauge and hide it someplace. Makes sense. Surprised there isn't a sender already seeing that trans temps are so important.
Do I just look for the biggest cooler I can fit up front since I won't be using the radiator?
I don't want to completely block the condenser either I would guess. There is room off to the side. The grill opening area on this car is huge.....

Thinking about going this route, and mounting under the car? Like I said, I have room up front off to the side as well.
Anyone ever use one of these? Looks like they are made well and get good reviews.....
Could really solve this issue for me.

Trans cooler I'll tell you what I did and you can take it from there. On my '33 ****** there was no room for a cooler anywhere except laying flat 2 inches off the floorboard just in front of the driver back wheel. Used a small square cheapo cooler with no fan. I put a temp sensor in the pan of the 4L60E. As mentioned earlier the temp was slow to climb and would level out about 150 degrees but would jump up to just under 200 when climbing mountains. On the down side it would fall to 120. The key here is that when in lockup the trans was easy to cool. I don't understand why you can't put a fitting on the radiator to go to a hose then to your trans solid lines. As a side note you can have too much cooling. Parts of the trans are aluminum and parts are steel, designed to operate at 150 degrees.

The GM lines are aluminum 3/8" ID but oversized OD. Can't flare it and am not thrilled with jamming a hose over the smooth tube and hoping a clamp holds everything together.
No good way to adapt to the push-in connection on the radiator. Easy on the trans side.

you can bypass the rad cooler - no issues at all - matter offact it will improve things as the 185-190 degree coolant temp isnt taking as much heat away as you may need
I would not worry too much about a temp gauge unless you are towing as it is unlikely you will ever get over 200 degrees with a decent cooler up front, and every day driving - there are tens of millions of vehicles out there with out a temp gauge
if you are insistant on using the rad cooler and lines - take the old lines and cut about 4" off, clean up the lines and get someone to silver solder the fitting of your choice on the end of the lines to adapt to whatever lines you are running, and then install the cooler inline

Trans cooler When I put the engine/trans back in the '39 I must have hit the trans cooler line and it cracked right where it goes into the trans. Big pool of red liquid! Notice in the picture that the end has a small single flare. I was able to use my flaring tool to do this with no problem at all. Rubber line will work over it and a single clamp secures the whole thing. Trick is to not flare too much. Gsteele, not sure if there is actually 50-60 degrees difference from coolant in the trans to trans pan but worth research.

Took a look under the car and there really isn't a good spot to put the cooler with fan.
Need to look up front. Don't want to cover up the condenser. Not sure if the Derale with fan makes sense if I put it up in the grill area. Need to think this through some more before spending more money on this.
Nothing's simple.....
