hey guys, new to the forum. i picked up a 624 last november, the first winter went off without a hitch. really enjoying this machine. this winter...not so smooth...i still have warranty but everything is closed here now due to the world falling apart. my main issue is the transmission. i typically turn the blower on for a min or two before moving it and allow it to warm up. using it the last couple times ive noticed that it will not move forward or reverse right away when its cold. i have to hold down the drive handle for a few seconds before it will move for the first time...after the initial forward or reverse it is fine and has no issues with drive. the cables seem to be adjusted properly(considering it moves forward and reverse without issue once warmed up) and the fluid in at the "high" level...any thoughts? thanks in advance!!
