one last tranny question

[Dale Hajas]

One more question before i remove the transmission. I'v driven the car and the transmission works fine, all gears shift smooth until we get to operating temperature then the problems start. The tranny doesnt appear to be slipping but it feels like theres something holding it back, the fluid smells burnt. Could this be a torque converter? is the tranny shot? could this have anything to do with the tss system?
Thanks all,
Dale
