Tell me about it. My 2000 Montana has also started to fall apart soon after I decided to purchase it after the lease -- front wheel bearings, 2 rear wipers, electrical wiring and to top it off, a major leak in the head gasket manifold caused a motor meltdown which required a total replacement of the motor with a reconditioned one!
Three months after the new motor was installed the car is again back in the garage since it continually fails to re-start if shut off only for a few minutes (e.g. to fill up the tank) while the engine hot. Mechanic says it may be the gas pump which like everything else doesn't come cheap. Anyone else experience this same problem? Would love to trade but am still paying for it!
#1235 of 1485 99 transport/montana transmission problems
Jul 05, 2006 (6:34 pm)
We need help and we need it fast. I hope someone can shine a light on this delema. We just bout a 99 transport in April of this year.I am primary driver as my husband works out of town. Anyway, in April when I drove on the highway, the transmission was straining to shift then it snapped into gear. My husband said, you just need to get used to it. Well when he drove it on his days off he noticed the problem too. We took it to a GM dealer who found a code and said the fluid was burnt. the dealer we bought it from went half on the bill and had a *good used * transmission installed. This was June 12/06 and we got a 90 day warranty. Right away we noticed the gear indicator lights would go off while driving. Sometimes they would come on other times not. Sometimes a bump would bring them back. I noticed the long shift again as well as shudders and a howling sound when you reverse.
I spoke to a mechanic and he said to have the computer checked out. It is now back in the shop and I am waiting for word on it. Can anyone relate to this or offer some sound advice? It would be very much appreciated.

I have recently replace the transmission on my 1999 Pontiac Montana. It only had 68,000 miles. This is the second GM car that I have to replace the transmission. The other car was a 1994 Lumina Sedan. They both have the same transmission and the same mileage when the tranny failed.

The Montana and Transport are the same. We have 154,000 KM on ours. Not sure how that comapres to miles.

Well we had the transmission checked by another shop who specialize in transmission work. They found nothing wrong. The hard shift is still there but intermittent and they were unable to recreate the problem. We decided to drive it until it breaks down. Then today we went for a drive on some gravel roads. We were about 40 km form town and all of a sudden there was this loud grinding and a click, click. Thank god my husband was driving. Anyway, here we are 40 km from town and the van has this god awful noise. My husband took off the front passenger wheel and found out a bolt had come out of the brakes causing the callipers to come apart and grind on the rim. We had a cell phone so called for a tow. the van is sitting infront of our house. Has anyone had this happen?

It's your heater core going out. I guarantee it. Costs about $300 dollars to replace at a shop. You can also try a can of Bar-Leaks which will plug the leak. My experience is this stuff only last for a couple months.
#1243 of 1485 Sluggish/Hot Re-Start Probs
Aug 03, 2006 (12:55 pm)
Service engine light came on my 2001 Montana and car was having serious hesitations and restart problems when the engine is hot. Garage said they found a splice in one of the wires which was causing misfiring to one of the spark plugs -- so changed the wires. More hesitations probs, took it back and they found a cracked spark plug -- so changed the plug. Hot restart prob persisted,, forcing me to wait a good 20 minutes to allow engine to cool. Once the garage was able to recreate the non-start problem (would just keep turning over), garage said the fuel pump was malfunctioning due to low pressure reading -- so changed the fuel pump. Hesitation problems have come back and the other day the car almost stalled on a hot restart -- putting into question whether the culprits were in fact the wiring or the fuel pump in the first place. Could the oxygen sensors be the problem to the sluggish performance, as well as the real reason for hot re-start problem? I kept the old fuel pump and am wondering if it can be tested once removed from the car to see if change was unecessary??? Also read that "GM motors don't like Bosch Platinums +4s" -- I know nothing about plugs and have no idea which plugs are on my vehicle. Grateful for a response before being hit with more repair bills...
