Shifting issues
Hello, I'm having an issue with my 2000 A6 4.2 transmission. I replaced the TCM recently after the drains clogged and flooded my module. Only one small problem, after clearing codes ( vag com ) on TCM and ECU, the car only briefly engages in drive ( about 1 full second ), reverse works fine. Looking at the measuring blocks, I can see the solonoids energize. The measuring blocks do indicate that the MFS is operating and sending gear shift selector location.
When it's engaged for that 1-1.5 seconds, it does not slip, you can " smoke " the tires. After that second, it feels like nuetral, no matter what gear you select. One thing I did see displayed that has me puzzled, when looking at the measuring block that shows what gear your " actually " in ( not what gear you selected ) it displays " 1M in when park is selected, it also shows 1M when " D " is selected. Is that normal? " N " shows up when in nuetral, " R " shows up in the block when in reverse. Why does it show 1M in " D "?
Thank you for the help. Low fluid issue?

I would take a close look at the plug that plugs into your tcm pull on the wires and make sure nothing has corroded and is coming apart. I would also coat it in dielectric grease to stop any ongoing corrosion.

pins and things
I have cleaned my connector pretty well and sprayed with contact enhancer. I'll start taking MA readings for each solonoid. I did check the trans. fluid last night, with vehicle at temp., plug removed. I found that there was no fluid I could touch with my finger through the hole. I also expected to lose some fluid through the hole when I shifted it into reverse, but didn't.
