Hi,
What size transmission cooler lines are on my 2001 ram 1500 5.9 4x4. I believe they are 3/8 not for sure truck is at shop. Ordering a trannsmission temp gauge now. I want the compression style fitting, that goes on cooler line. Needs to go from line size to 1/8 npt. A link would be great.
Thanks,
Ben

 

well this dont answer you ?....... but you want to put the sender in the front servo port

 

3/8...

 

No, the servo port doesnt give you the best read of temp. of the system, line out to cooler is where I will install. Thanks dhvaughan

 

It is 3/8 line and the fittings that attach to the flared ends are JIC fittings. They may be difficult to find.

 

I was just going to cut line and put tee in, they make one I believe.
