Hi All

My 5r110 Torqueshift is intermittently chattering on take-off in 1st gear. It also has a long delay only when you put it in drive - reverse is fine. It is a bone stock unit. I checked the line pressure and it was wobbling all over the place - worse on tip-in, so I changed the Line Pressure (PC-A) solenoid. The pressure is steady and within spec now, but will still do chatter on occasion. It really feels like a pressure/control issue to me, rather than a smoked tranny issue. But.. if I allow it to continue to chatter, it will rip itself apart pretty quick.
Ideas anyone??
Anyone run into the same issues?
