Re: Tranny Fluid In My Coolant!!

Sounds like your radiator is junk. The coolant tank in the radiator that cools the trans fluid is leaking into the antifreeze coolant tanks. Hope it didnt let coolant into your trans. I seen this happen before and the trans got smoked.

Flush both systems and get a new radiator ASAP.

Man, just blow it up. I'll send you my car at the same time and we can watch a double explosion happen.

Re: Tranny Fluid In My Coolant!!

Hey, could you guys yank the rears and send to me before ya'll blow 'em up? That way I could still drive my ride 'til the funds for the 9" are gathered. . .

It's definitely a leak in the oil cooler in the pressure tank. If it's only a month old the manufacturer should replace it. Unless it's a used rad you've only had a month. Any way, flush both systems but you can get a tranny cooler and use that in place of the P-tank (Rad) cooler. You'll need to block off the cooler lines to and from the Radiator or anti-freeze will leak out.

Re: Tranny Fluid In My Coolant!!

Replace any hoses that would contact the coolant/trans mix. Upper rad, lower rad ect. Was the fluid in the trans clean?
