Transmission oil in my coolant
5 Answers
You need a new radiator. You can buy separate transmission coolers at almost any auto parts store. I like Derale myself. Look online.
That's what I thought and got one had the car flushed and still transmission oil in coolant
That is because there is a leak between the two different parts of the Radiator. If you have coolant in the transmission you should change the fluid. Same thing for the cooling system.
I have a 2010 Audi A4 1.8T (Ambient Plus Model) and I saw oil in my coolant reservoir bottle and couldn't trace it's origin. A couple issues turned up 1. Coolant Housing Unit ( under rear engine ) needed to change. System flushed but oil kept appearing in reservoir bottle turns out I need a new radiator (which i'm told has the Oil Cooler built in). Problem : Water has already infiltrated the Tran. Proposed Solution short of a Tran Overhaul (as first gear now bucks before engaging) Buy new radiator flush system out (to eliminate Oil and water mixing) replace Tran Oil and hope it improves.
