Hello All,

I went through the intake manifold replacement fiasco this past weekend on my 2003 Montana. Along with the gasket repair, I replaced the spark plugs. The job is complete but I have 2 problems.

The first and primary problem is that the transmission is slow to upshift since the repair. It's noticeable on all upshifts, but most notably on the 1-2, 2,3 shift. I had the battery disconnected for the duration of the project but did not make any changes that should have affected the operation of the transmission that I'm aware of. Any ideas?

Secondly, there is a small solenoid with a vacuum line attached to it between the throttle body and the EGR solenoid. It has an electrical connector and a vacuum line that goes to a tee right behind the throttle body. I see an open port on this solenoid that pulses air when the engine is running but cannot find a hose to connect to it (and don't remember removing a hose). Any ideas what this is or if it should just be capped?

I have no CEL or warning lights. The van seems to run fine with no loss in power or hard starting etc. Seems like the repair went really well but the transmission thing scares me a little bit.

Thanks in advance
