When you install an aftermarket transmission cooler, do you have to put new cooler lines from the transmission or can you extend the stock lines.

Some do and some don't come with rubber hose.Yeah doesn’t Kit come with rubber hoses that extend? It’s probably just me, but those would make me nervous as hell.

Mine has been good with that setup for almost 5 years now. Keep in mind I only drive it about 5,000 miles a year.I’m sure it’ll be fine and will make transmission happy.
Bad advice, especially for anyone who does genuine winter driving.he told me to bypass the stock cooler in the radiator and install a Hayden cooler in the front of the rad.
In warmer climates like here in Texas, I do the GM method myself. From the trans into the upper radiator port, then from the lower radiator port to the inlet of the auxiliary cooler then back to the trans. This is how both my Express van and Tahoe were factory plumbed.Bad advice, especially for anyone who does genuine winter driving.
The "trans cooler" in the radiator does two things: cools trans fluid that's hotter than the radiator coolant; which would be around 160--170 degrees. It also warms trans fluid that's colder than the engine coolant, speeding transmission warm-up in cold climates.
In short, the in-radiator "trans cooler" stabilizes the trans temperature so that it's held within normal operating limits. A stand-alone "cooler" cannot warm cold fluid, and--depending on the size of the cooler--could "over-cool" fluid.
There's basically four ways to plumb a "stand-alone" trans cooler. The way I recommend is to route the hot fluid into the stand-alone cooler first, then to the in-radiator cooler, then back to the transmission.
