Trans Rumble 2019 update

[AnthonyRI]

Spoke with my local dealer on having my transmission flushed with the newer spec’d fluid which was scheduled for tomorrow.

dealer called me yesterday and has to postpone per gm orders until a gen 3 fluid arrives. Service manager stated that this is the third series fluid and will only be done if gm allows it after submitting the pico scope results. Also the new fluid is being sent to warmer climate states before the northern cooler states so I will be stuck waiting for a few more weeks.  I’ll let everyone know how I make out once and if I pass the test.

What are symptoms of needing a flush? RPM’s bouncing while on highway at cruise. 

 

Only thing I’ve noticed with my 2018 with 6900 miles is a forward lurch if I rev it in park when cold.
