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 ? **** If anyone has had similar issues, or has suggestions feel free to E-Mail me your responses... : dj_nikki  verizon.net >> just write "montana troubles" in the subject line. This request expires after September of 2009 ! ~ Thanks, Have a good one.

http://townhall-talk.edmunds.com/WebX/.f0fb401/50 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 | |
