Default Replacing Tranny lines?

I'm doing some resto work on my engine compartment and planned to replace the M38 transmission lines but finding the ends that connect to the tranny tucked up there pretty good.

Anyone else tackle this with engine in the car with tips for replacement? I can barely get my flare wrench up there for than with no room for wrenching.

Could unbolting the crossmember while supporting the tranny with a jack help?
When it's out you can lower the jack and the tranny motor combo will pivot around the motor mounts. Ofcourse you have to remove the exhaust, watch the dizzy to firewall/wiper motor clearance and the fan to shroud clearance. I did it this way to change the governer and to tap the cap into place.

Hello Tom. I used these with a long extension and 3/8 ratchet. They came loose but were tight. Forgot if they are 9/16 or 5/8. Good luck with it. mike...

I agree - I use those as well - no need to lower the trans.

Craftsman, Snap-On, Matco...about all the good tool providers.

If you have good English, 6-point "box" wrenches available, you could make what you need by cutting a slot in one 'flat' of the wrench, cutting off most of the handle and welding something with the right size socket (for the extension that is needed to turn that wrench) to the stub end of the wrench. That would get the job done, if you can't find those flare wrench pieces.

Those flare fittings have to be tight to seal transmission (hydraulic) fluid. And a flare (tubing nut) wrench must be used to prevent rounding off the corners of those hex nuts. With no room for normal tubing wrenches, those crow foot adapter wrenches are the only tools that will easily loosen/tighten those fittings properly.

Yeah...figured that out when I was removing the radiator and felt the std wrench slipping. Picked up a set of flare nut wrenches to break those nuts free of the radiator without destroying the radiator.

Thx for the tech tips!
