Transmission cooler lines HELP

Post by DR.Camaro »

Hi guys and gals, I am new on this forum, first time.
I inherited my dads 1998 Bonneville SSEi when my dad past 3 years ago. The car is been sitting in the mom's garage for 9 years sins he got sick.
I am have been starting the car up every once and awhile, last year I started the car up and I noticed a transmission fluid leaking, looks like from the transmission cooler lines. I stilling need to verify that 100%, (I am license GM Tech). Unfortunately my work can only check GM dealers across Canada (yes I live in Canada) the upper transmission line is discontinued from GM.
Need help locating this line, is there a way that someone find out if any GM dealers across the USA have them please.
Thank you

The fix for this is carefully cutting the ferrules, removing the soft line line then replacing with fuel injection line and quality and/or doubled up hose clamps.

You can also have a shop that handles hydraulic lines replace the rubber section as well, assuming it is from a rubber hose failed

Great idea but I am looking for OEM line. Maybe I was not clear in my initial post (on me sorry) I am looking for a GM original. I just need someone to call or go to the dealer and ask them if they have the lines in stock or to check if any other deal in the US. If someone lets me know what dealer has the lines in stock i will call them.
Thanks

Thanks for your help I just remember about RockAuto. They have the lower line aftermarket and the upper I can still order from my work.
