#44 of 71 Pontiac Montana BRB and BCB transmissions by bckyrdmech

May 28, 2008 (7:46 am)

I have a 2000 Montana that I was told the PCS needed to be changed in the transmission. My son decided to drive it for a short distance after that, and now it does not have any forward motion at all (it feel like it is slipping), but reverse works fine. He also said that overdrive quit working on him shortly before the rest of the forward motion went. Could this still be the PCS? I am considering just replacing the tranny, and I would do it myself, but here is my question for that: If I were to do this, what is the difference in the BRB and BCB transmissions, and how do I visually tell the difference to make sure that it is the correct version? I was told it currently has a BRB transmission.

#45 of 71 whining when accelerating on my 1998 transport montana by tranny08

Jul 01, 2008 (10:16 pm)

my 1998 transport montana has a whining noise when stepping on the gas and sometimes when idle. It goes away when just coasting with your foot off the gas pedal. As soon as I step on the gas it starts up again. Brought it to a mechanic and he said to replace the whole transmission. All he did was put it on a hoist and said he heard noises in the tranny and something is ready to go on it. My check engine light is on and he didn't even check that out. The van switches gears real smooth as if there is no problem. This all started when I ran out of gas one day. Any help with this issue would be greatly appreciated. Thanks in advance

#46 of 71 Hard shift sometimes by pacecar68

Jul 18, 2008 (10:28 am)

I have a 2001 Pontiac Montana with about 48K on the odometer.... Sometimes it will shift hard. You start it up and all the shift points seem hard. You can then turn the van off restart it and the shifts are all smooth....I had the tranny serviced (pan drop method) at 30K and plan to do so again at 60K. Is there something "electrical" or "computer-related" to consider regarding the occasional hard shifts?

#47 of 71 1998 Montana, no forward or reverse by brm5114

I was about 100 miles from home. Had been running fine for about 30 minutes, all of a sudden tach ran up and trani was in nuetral. Pulled over and tried all gears..nothing! Let it cool down, tried again ..nothing. Had it towed home, dropped pan and drained old fluid. New filter & fluid..still nothing. Shift linkage is good. Check engine light had come on a week before..latest code # P1870 "transmission component slipping". Car has 199K but engine still running well. Any chance this is something simple & inexpensive?
Anyone experience the same?

Hello every body
2 Problems - 1 : Driver side window power switch burns every time.
                    2: late kick - shift change- 2nd & 3rd Only..
 
When It passes 60km/h speed it runs well but when you stop & move
that's when the kick and shaking noise come.
 
I had a year and half & still driving because it's very expensive to change
the Tranny which a lot of people said is the issue.
 
Any help would be appreciated.
 
Thanks in advance.
Soulman

The power window switch for the driver side is wired in series with the switch for the passenger side. One of the two switches may be shorted. If not, suspect the power window motor.

Well guys, transmission problems hea? You are not alone. I have a 2000 Montana which started acting up just over 1 year ago and currently have 150k. It's the same observation as most montana's with trany trouble: error code slippage, hard shifting, turn off engine to reset codes and runs ok until it slips again a few times and then back to hard shifting, wineing noise when in hard shifting mode. Did research and most often it is one of the selunoids (sp?) inside the transmission (there are pictures of a worn one on the internet). Anyway, quote is around $2750 to have the transmission replaced - if to speak to low-cost or any transmissionn shop that works with montana's they will have a refurbished transmission ready to install in their rack - most shops suggest that it is not worth the time/effort to take apart and diagose and risk missing components that need changing out that brings up the bill anyway. For city driving i'm planning on just letting it die then replace it but taking it easy on the peddle when shifting as it is hard on the engine if your flooring it when it is doing this. Unless anyone has any success stories where a shop has taken appart, replaced all parts (do a proper job) and put back to gether for the same price as a new one or a re-built one then i'll probably just stick it out a little longer unless someone can convince me otherwise...

I had the same issue with my '05, hard shifting after 10 minutes of driving. I researched it on automotiveforums.com, and there was a member there that installed a $30 shift kit from zzperformance.com on his van, and it stopped the hard shifts. I did the same, flushed with Dexron VI fluid, and all is well.

VERY curious about the 'shift kit' you instaleld... can you tell me more about it, where I might find it, how you installed it, how long it took and what you think it actually does? Thanks !
