Transmission problems :~{ by candlemaker2

We need help and we need it fast. I hope someone can shine a light on this delema. We just bought 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.
 Thank you

The indicator lights going off sounds like an electrical connection issue somewhere- maybe a loose plug. No advice on the other problems, sorry.

Thanks for the reply jerrywimer.
 That is what we thought too. Now we are wondering if maybe it is some kind of warning that something is going on within the transmission. We used to have a Dodge Caravan . A couple of times all the indicator lights under p r n d 1 2 etc would come on all together. Then we started having transmission problems with it.I don't remember what it was but it was something expensive to fix.

The only reason the electrical connection came to mind for me was that I had a transmission replaced on an 88 Chevy Beretta several years ago. When we got the car back it would intermittently act up in a similar manner. The dealers' mechanic pulled a harness loose at the transmission, sprayed something in it to displace moisture, then made sure it reseated properly when he put it back. No more problem!
 
I hope you have similar luck fixing your problem.

yes, we had thought it may be something like that too.
It is back in the city at the shop that did the original work. They have a transmission specialist so I hope he can figure it out.
I hope it is that simple too, thanks

Stop hoping for things and take it to another garage in town, preferably one that deals with transmissions. Get an independent appraisal of what is wrong and how it can be fixed. Even if you have to pay for this, it will be worth it. Then go back to the dealer you bought from (if there is remaining warranty) and get it repaired properly. If they wont fix it and it is still within the warranty period, go to the Better Business Bureau. If you are past warranty, then just go to the most reliable repair dealer in town, get them to fix it right, otherwise you will be stuck with many more days in the repair shop and possibly another ruined transmission in the near future. Just my two cents.... Dave

Thanks,
 Actually they ran a host of tests and said the transmission is OK. The dealer is getting it into another shop Mon. to have the electronics tested. he said the mech told him he thinks it is misfiring and that is why it seems like the transmission is not shifting. I asked what misfiring meant and he said something within the computer that tells the trans to shift etc.If that is the problem, who knows what it will cost.
The dealer is being great, the van has no warrenty but they are covering at least half of the repair cost.

2001 Montana Timing Belt Q by rogerhunt

I have just bought a used 2001 Montana. The seller tells me that he hasn't had the timing belt changed. The vehicle has 96,000 miles on it. Should I rush out and get it done now or do I have any leeway ?
