Super pissed because I now have to take it into the shop and I haven't even had it for 12hrs. Dealer was semi helpful in arranging a local mechanic, but I am worried it may happen again. And from all the posts in these forums my confidence if definitely hanging by a thread.
Any thoughts as to why my truck moves like a castrated dog.....???
Thanks
an ideas?
an ideas? oh I forgot to put the # I got off of the tranny.. 15671928 no idea what it means.

thanks, saintal
I am back to square one. would this be I have to get me truck plugged back into the mechanic computer and re set ????

It decreased the tendency of the wheels to slip and allowed the clutch to slip instead. Whatever the reasons, it worked. Feather the clutch in second and you eased off on your way.
What TSB?
IT WENT INTO DRIVE AND REVERSE FOR A SECOND AND HASNT DONE IT AFTER THAT. OTHER THAN THAT IT DRIVES GREAT IN GEAR 1,2,3.
Should the tranny make a slight "honking" (cant describe it any other way) sound when taking off from a stop? It doesn't happen all the time and I never heard it when I test drove it. I have not towed anything as of yet.
I also need to know what transmission is in it.
Thanks!

1996 Chevy Pickup truck
V6 4.3L engine
When I accelerate from 1st to 2nd gear (10-15 mph) I get this noticeable clunk noise. It all started on Monday (09-21-2009), it just started out of the blue. No gradual noises, no warnings.
I believe it's coming from the transmission. And now, it's beginning to leak. I see wet spots under my truck that I've never seen before.
What is this? Do I need a new transmission? I hope not, I don't have the expense for this.
Any help would be appreicated.
thanks

Being a GM guy most of my life, I bought a 1995 GMC Sierra W/T 4.3 V6 w/5 speed tranny in March '95. Tag says truck was built in Canada. With 6 miles on the odometer, I left the dealership when at the moment I first let off the clutch, the floor shifter popped out of first gear and slammed into the palm of my hand, nearly breaking my wrist. I simply thought this was my error of not having the shifter properly engaged, so I went along my happy way. About a month later while at a stop light, the same thing happened and again a month after that. I brought the truck back to the dealer to investigate the problem. They kept the truck 2 days before calling me to say they could not duplicate the symptom or find anything wrong. The problem continued once or twice monthly until it began occurring more often. The truck went back to the dealer 5 times thereafter with this problem. Each time they said they could not find or acknowledge any tranny problem.
The truck's first year saw over 65k miles using 1st gear only at times when necessary (I had gotten used to it). By the third year, the problem had become so severe, it occurred almost every time while starting out from first, until at 278k miles, the tranny finally locked up one day requiring the truck to be towed to a transmission shop.
The truck has always been serviced by the dealership during warranty. All fluids were replaced with the proper GM fluids, but they never would acknowledge this problem. I finally stopped using the dealership for service. Warranty had long run its course.
At my expense, I had the tranny replaced with a used low mileage one as the shop said the original tranny had "melted" on the inside and although they had seen this condition before, it could not be rebuilt. One week and $2k later, the truck was serving me faithfully on the road again, only this time, for the first time in it's life, I was able to use 1st gear normally with no problems at all. Wow!
At 427k miles, the second tranny became extremely difficult to shift into first and sometimes second gear. Another visit to the shop for a $1.6k shifter kit overhaul modification of some kind, it was almost like new again. They told me to "baby" it and it might get me by for two more years.
Today, at 1/2 million miles on the odometer, this second $2k tranny with it's $1.6k shifter mod is now beginning to "melt down" on the inside (as they described it) like the first one did, although, it has never popped out of 1st gear like the original tranny did. Oh well, I can't complain! Will I go for a third tranny or not? After all, this truck has served me VERY well with an engine having never seen a wrench, burns/leaks no oil from oil change to oil change, performs reliably as a GM built work truck should and still gets me 23 MPG to this day! This leaves me to ponder one valid question:
Why can't GM build transmissions to perform like that V6, 4.3 engine???
I know of several people who own a Silverado with this same problem, but it seems the correct answer for each problem is not easy. Most all newer transmissions are now electronically controlled and there seems to be several issues that relate to this hard shifting from 1st to 2nd. What may be the answer for one "hard shifting" problem may not necessarily be the correct answer for another, so it seems.
I'm not a transmission specialist, but it seems reasonable to conclude that heat will destroy an automatic transmission quicker than anything. Towing heavy loads produce lots of heat. Dirty fluid will produce excessive wear and tear, and ultimate failure of mechanical parts. It's just common sense. Keep the transmission cool as possible, keep the fluids clean as possible and it will likely last longer ... but things can go wrong also with the various mechanical and electronic components that must ALL be working properly in order to render proper operation of the transmission.
I realize this may not be much help in your specific problem, but I thought I would mention this information since it is the same problem you are experiencing. There are many fantastic guys here that can shed more light on this subject, so a little patience and maybe we will both learn some interesting facts in the days ahead. Keep us posted on your findings and I'll do the same. Best ...
