Yep. That was it. Replaced both rear shocks and no more banging noise. Thanks for the advice.

I’m taking it back to the shop tomorrow and I’ll have them look at that. Right now it doesn’t seem like brakes, although that’s when the noise occurs. Thanks.

Not on light application going down hill but on heavier braking when I stop it starts banging. Today I can feel it through the seat.

My 2012 TC still has a banking or knocking noise from the rear when I apply brakes. This noise has happened before when it needed new rear brakes but I had them replaced and drums turned last week. The noise is still there. Usually when I have driven for half a day and they’re warmed up but sometimes when they are cold in the AM. Any ideas?

UPDATE: Today, I’m not getting any trouble codes but a couple of times now I have lost overdrive. Stopping and shutting off the motor for a couple of minutes and it’s back just fine. This has to be electrical rather than mechanical. But I’ve been wrong trying to diagnose later model cars before.

Well, he told me which code w came up (P0171 lean mixture) and told me it might be an intake manifold but it was 5 minutes before closing. After he cleared the code overdrive came back and it ran well until today. I checked the code myself (same code) and after I cleared the code overdrive came back again. I’m thinking this might be s computer problem rather than a transmission problem.

Weird thing happened. On my 2012 TC Taxi with 330000 mi, check engine light came on and it wouldn’t go into overdrive. Just 3rd gear. I took it to my mechanic and he came up with code P0171, too lean fuel mixture. Said maybe a vacuum leak and cleared the code. Then it started shifting as normal going into overdrive like nothing happened. I’m waiting for the code to set up again and I’ll clear it myself to see what happens. I don’t see the connection but strange stuff happens when you’re over 300,000 miles.

I just bought a 2012 Transit Connect, CNG engine, with 327,000 miles on it to use as a taxi in Orange County, California. That’s a lot of miles but it didn’t cost much and it runs really well. It has been used as a Taxi since new and has had regular service and repair. Really, my only complaint, other than the lack of power, is the radio reception in fringe areas. Maybe a new antenna. The power issue isn’t really an issue as I’m getting used to it. Anyway, it makes a pretty good taxi.
