#17 of 26 Rear clunking from air shocks
Mar 12, 2009 (6:30 pm)
I have recently replaced the air shocks because there was a clunking noise comingfrom the rear of the van. I still have the problem only when the weather turns cold. Is there anything that is causing this to happen or is it just part of what it should do. Any suggestions would be greatly appreciated.

I have read other posts that someone who had other work done on their van and later found out the jack in the back was making the noise when it got cold... banging against the frame inside the jack compartment. I know you've probably looked at this but just an observation. Having someone ride int he back when it starts clunking could help.

I have a 2000 Montana that has had LOTS of issues,...at 94K the check engine light came on and the low fuel light came on. I put $30.00 in gas and the low fuel light stayed on,... then it stalled out & wouldn't start, it acted like it was out of gas! I had it towed home, & the next day it started up just fine,... but while it was sitting there idling, it made 1 hell of a noise & stalled out,... well I had it towed to the dealership & they said that the Engine was Done !!! They said something went out in the lower end. So I had a used engine put in it that had 60,000K,.... Now before the engine trouble, there was no tranny trouble,... but after I got it back it started whining in reverse, so we checked the fluid level, it was down, we were told that it apparently had an air bubble in the system from the engine replacement,.. so anyway we filled up the tranny & shortly after we started noticing that the tranny would shift really hard and whine (but only Sometimes!) Well I took it to a tranny shop & he told me that the tranny needed replaced Eventually,... I asked how long & he said (A week -- A Year-- ?) who's to say...... Well It's been about a year, & in that time we have figured out that when it starts acting up, you have to pull over & turn the engine off, & turn the key backwards & fowards to the point of Auxiliry power (3 times) & then restart it, & it would reset the computer & run fine again,... however, recently the old 1-2-3 start trick doesn't work all the time ,... or it will work, but then about 300 feet down the road it starts acting up again,.... it is progressingly getting more troublsome,... my biggest worry is that maybe it's not the tranny as much as it is the computer,.... Should I put $2,000.00 into rebuilding the tranny or should I just say hell with it & buy something else ?

You probably don't want to hear this but my van has been doing this for over a year now. I am NOT an expert but have done much research and this is what I know. It is likely, not garanteed, that the primary pressure selunoid in the transmission is worn out or it is dirty. It controls the presure on trany plates. The computer detects transmission slippage and after a certain amount of times it sends a signal to the selunoid to go FULL PRESSURE as a safty measure to save your clutch plates from slipping and burning up which can hatch your trany really fast. Either your plates are worn badly or your selunoid is worn/dirty causing an incorrect amount of fluid pressure which in turn creates slippage which in turn the computer sends a signal to go full pressure. Depending on how you drive, hard shifting can really strain your transmission. The dealership/trany shops will want to replace rather than fooling around with the amount of time it takes to take appart transmissions and "miss" something in the process... rebuilds are probably a good option when you really consider this. I am waiting for mine to physially fall off the van as i'm driving taking precasions to ensure if i'm on a family holiday that I know exactly where I can have the van towned (AMA coverage) in order to have it replaced and how much it will cost.... about $2500 in Alberta/BC. The effort to replace the selunoid is ~$200 parts and about $700 labour (estimate) - I am also considering this but to the transmission is hours of work taking things off and dropping from
van. I know, probably not what you want to hear. Once it is opened up you never know what they are going to find and you'd actually have to trust them b/c you/I don't know crap about what really needs to be replaced. There are pics on the interest of the selunoids worn for the montanan but took awhile to find them.

I have also read some posts where montana owners change the selunoid and the problem continues.. but they never did find out why so it's a crap shoot but a good one.

Something I discovered over the past week... apparently there is something called a "shift kit" that you can install on some transmissions of which are for montana. The shift kit somehow bypasses the PCS and is signficantly less expestive/difficult to replace - simply dropping the trany pan you can install the $30 part which is available from zz??.com. Don't know much more than that... search automotive forums for more info... Cheers, Kennie

did you find any adapters for the air hose connectors?

whether you may have fixed the issue on my sisters 99 montana i lookied in the hatch area seeing on the drivers side there is a small area where you can hook up a 12v phone charger or some other devices next to it is a switch its a on and off switch for the compressor for the air ride assist turn it off will keep the pump from working i turned hers on and then turned the vehicle key switch on and almost isntantly it came on after a few mins it shut off but her issues is that i have to replace all her rubber hose lines as they are so rotted out no air is filling the shocks so that is a simple job to do but i hope this helps you out

Hi, I have a 2008 Montana SV6. I had a similar problem so I checked the fuses on the right side ( to the right of the glove box) Look for fuse #2-20A or #15-25A These are both side by side, the are marked as ELC and the panel, I looked at both and it was #15 that was blown It worked after I changed it. Hope this helps.
