How hard would it be to install cooler lines without dropping the trans? I already have a cooler installed on the radiator, I just need the cooler lines.
Alot of this will depend on what fittings are already in trans if any and what type of line you'll be running. You can gain alittle room by dropping trans cross member and letting it hang. If its anything other than factory type hard lines that snap in I'd be dropping the tranny to save the headache.
Not sure how your current cooler is set up but if theres any rubber hose and clamps in the system now its a good time to upgrade. Either hard line with flared ends or AN.
When I disconnected the lines when it had a 4l60e I think it was the factory steel to rubber lines. Or most of the lines where metal lines. It's been sometime since I swapped transmissions.
I was hoping I could use some type of braided, rubber or flexible hose and just run the lines from the trans to the cooler without dropping the trans.
I don't think there are any fittings in the trans either..
You do have enough room to change your tranny lines if you pull the tranny cross member off and let it sag down.
Pull the stock fittings out which are 1/4 NPS and run -An fittings and braided lines. Let me know if you want fitting and braided line parts list.
Coming out of the transmission you will put something like a 1/4 in NPS to -6an fitting in there
I just thought about it, I think my lines hook to my radiator.. Does that sound right? Or do all transmission lines hook to the transmission cooler?
Do you have a aftermarket cooler?
The stock cooler is in the radiator. Even with a aftermarket cooler some people still go threw the stock cooler then to the aftermarket cooler but I think most bypass the cooler in the radiator and just use the aftermarket cooler as you will see lower temps.

Okay that makes sense. I have a aftermarket cooler that is attached to the backside of the radiator. But when the 4l60e was removed the cooling lines were hooked up to the radiator.
Should I hook it back up to the radiator or the cooler? I'll try to get s couple pics tomorrow of the cooler.
I would by pass the radiator cooler and ONLY use the aftermarket cooler.
Okay sounds good. Also I hate to ask but can you get a picture of your cooler and radiator? I want to see how you have the radiator bypassed. I think someone just put bolts in mind to plug it up. I'll try to try to get a pic today.
To bypass the radiator you don't really have to do much. I didn't even put plugs in the holes. The stock tranny cooler in the radiator is just pretty much a continuance of the line that runs threw the coolant in the radiator which is not exactly cooling the tranny fluid.
I removed all stock tranny lines and threw them straight in the garbage. I did not plug the radiator cooler ports, just left them open. Then the two braided lines from my tranny shown in post #9, I ran straight to my cooler that is mounted in front of my radiator. I deleted my a/c so my condenser is not there anymore. I have cooler spaced about 5/8" from my radiator.
stock radiator cooler bypassed and ports left open
aftermarket stacker style cooler mounted in front of radiator with about 5/8" spacing
just got back from a drive around town and here are my temps
I must have a cheap style intercooler, my ports on the cooler (at least the top one I can see) is not threaded. It's a slip on style for rubber hoses. Think I can still use the lines you used?
That looks to be the b&m 70264 in which those fittings are welded in.
You can either buy a new cooler like the 70266 or just put -An fittings in the transmission case and slip the other end of the braided line over your current cooler fitting and use a hose clamp.
