• No transmission code
• No engine code
• Swapped transmission with same result
• Swapped torque converter with transmission
• Changed shift solenoids
• Swapped ecu
• Checked fluids

Changed wiring harness As well.
I have been trying to figure this one for a month now. Engine starts and runs great, but when in drive, the car doesn't start to move until about 2k rpms. I can put it in d2 and it'll move without issues. I can shift from d2 to 3 and still good. When I go to drive the issue starts. Rpms go up but there's little pull. This led me to swapping the transmission and still getting the same results.

I swapped the shift solenoids, then the ecu, then the engine harness. Fluids were the first thing I checked before all the major swapping. If anyone has any insight into this, or suggestions to try for something I may have overlooked, it would be appreciated.

 

What did it turn out to be? I have a 2005 and barely moves first thing then once it warms up won't move at all.
thanks

 

Internal ATF filter is clogged with clutch debris and restricts flow in the transmission to shift the gears?
