[scarborough]

are the transmission line threads on the 87 cutlass v6 2004r the same as bop th350 threads, not sure of the year

Dont believe the v6 ever came with a 2004r

the stock transmission line threads are the same. tube size is 5/16 with a 1/2x20 flare nut. all stock g body automatics used the same size.

Be careful, Pretty sure the threads on both these transmissions are straight thread (NPS) & are not tapered thread (NPT)

Correct, I have these waiting for my new trans install in the Monte.

They are the same thread, the angle of the lines are totally different, some bending will be needed. I have swapped back and forth a couple of times.

I believe the flow configuration is opposite for the 2004r from the th350.
Fittings are same size but in and out are opposite ports

thank for the info. the car has a 455 with a 350 transmission with the original transmission lines that's a little hack upped when i got it, the car was a gift, and i assumed the original transmission was a 2004r my bag. i installed a new american eagle radiator from champion. i would like to replace trans line want to make sure i purchase the right lines with the right fitting for the transmission and rad.
