Basics first: Trans fluid look good and properly filled? If not full find out why.

Just an "out there" maybe ---- is it cold enough for ice where you are? It's true that "bridges freeze first" and funky that you mentioned a bridge as the first sign of anything,

Arggh! Not the best holiday news to pass on to you but IMO that probably does mean the whole overhaul with "slipping" - "burned fluid" and especially if possibly the first trans for this??

If you wish it may buy some time to change out fluid and filter but I'd brace for the whole job,

Dunno - if it didn't work it would be a waste of the fluid and filter kit but that's all. I don't think it will cure anything but as said might buy time.

Sometimes fluid will age and start foaming which could make it slip with erratic pressures building up. There are even snake oil things to fake it for a while for certain types of troubles. They don't cure the problem and I don't really like snake oil attempts as some may make a real fix harder.

The oil being burned AND the slipping suggests it's worn. The fluid is by nature a strong detergent and plain proper new fluid can help. The dark comes from heat, slippage and the wear won't reverse itself. Shops really don't like tearing a whole trans down to replace bands and clutch parts only so the whole job is usually suggested. It's a bit labor intensive and nobody want failures right away because they got all they way there and didn't do the whole rebuild.

Were you going to change fluid and filter yourself or have the shop do that? It may not work but you have to decide on whether it's worth a shot at some more time - can't know that.

I'm talking about dropping the pan and changing the filter, gasket and the amount of (not all will come out) fluid that comes out with just that. Sometimes that's only 1/3 or so of the total system capacity with more caught up in the torque converter which may or may not have a drain on it - dunno.

What I would NOT do is FLUSH this trans - that I agree could instantly make it worse throwing debris where it causes trouble. Plain drain, filter and new fluid is not flushing it - let the new filter catch what it will in normal operation - that's all,
