A855 - 5 Speed

GFI designed, builds, and repairs the A855.
You and me both, and many others.
Not so, from what I was told directly by GFI and John.

In retrospect, it makes sense, he's never known when new trans will be available and doesn't service them or stock.

The John Huff road testing mentioned in the link indicates a surprising level of, how can I say it, maybe ‘Hill Jack’
An actual road test is useful to verify that a complex assembly was installed correctly. A road test is not a good measure of the actual assembly or even a good way to do the initial break in.
There are just too many variables in actual road tests. Traffic conditions, ambient weather, the vehicle condition, the driver and the list goes on.
A powered bench test would give them much more useable information. Common sensors available today could monitor noise, vibration, temperature, the shift process could be automated and monitored.
Powered bench testing would have far less installation time, be consistent from test to test and give traceable meaningful results. What GFI is doing as their final measure of quality is not an effective evaluation of the transmission.
