Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Get some braided hose, a few -6an fittings and you are good to go. Enzed can be quite helpful, I believe TUFFVQ used these guys when replacing his trans cooler lines and I know I intend on doing the same in the next week or two.
Yeh, that's a cheap fix.....
Cheaper than having to tow your car home because it's ####ed it's tranny fluid all over the freeway (trust me on this one). Sure a dodgy fix might last a day, a week, a year or even a few years but when if fails it will be costly; transmission hoses are high pressure lines, not something you should be patching with silicon.
