It didn't do this when i 1st bought it.but i'm with the guy that sez we should all get together and sue. but how does one organize and careyout this seemingly daunting task?open to suggestions. serdajohn@yahoo.com. the problem i'm having is when i'm driving anywhere between 35 and 70 cruising at a the same speed,the rpm's jump up for jost a couple of seconds then back to normal and it does it over and over.the dealer sed it mght be the torque converter and or silinoids.sounds expensive.what to do?

will cost about 3300.00 to fix this problem, there are no used transmission ,any where for this van, this is a big problem with 2006 Montanas, i have been told this at my Pontiac dealers, also it make is van almost ,of no value at trade in time, gm knows of this problem, Montana owners should all get together and and sue gm over this issue, i have purchased my last gm product, also thats one of the reasons gm have no more mini-vans think about........
