transmission oil, shady mechanics
how long would it take for NEW transmission oil to turn black??
some nine months ago my 2014 Mazda Cx-5 had some 120,000 miles, so I went to the mechanics shop to have them do a transmission flush on it Silly me I forgot to change out the transmission filter before getting it flushed. I was going to do that the other day so I dropped the oil and it was completely black. What are the chances the new oil turned black after being poured in?? I'm thinking this mechanic guy didn't do anything. |

Re: transmission oil, shady mechanics
they where supposed to do a complete transmission flush. I am now going to do a pan drop to change out the filter and simply replace the oil with some new since I thought the oil in there was new- ish. I figured it would be ok. The oil came out all black though, strange.

Re: transmission oil, shady mechanics
Usually a complete trans flush is done with specialized equipment, just a fluid change does not drain the torque convertor, so that fluid can contaminate the new fluid. I would ask how they flushed the unit.

Re: transmission oil, shady mechanics
If the vehicle has been driven for 9 months after a fill with clean fluid, slipping clutches, heavy use, and elevated temperatures could blacken it already.

I took it to Firestone, they're supposed to have a machine to flush out the tranny

I slipped up. I usually make sure the mechanics get the work done. Kinda just trusted it was done. Never again |
