#1941 of 6769 V-6 Vibration by bugsplat

Mar 08, 2001 (8:59 am)

Tried to post yesterday but it doesn't appear here. Maybe I was in the wrong site.
 
I have a 2001 V-6 2wd Xcab with 3.73 rear end, 1800 mi.. I've been getting a vibration as the tranny shifts under low load conditions, felt mosty through the gas pedal. Dealer said it was because the torque lock up was engaging too soon causing the engine to shudder under the strain. Needs re-calibrating, but they can't do it until GM gives them the new calibrations. Couldn't tell me if GM was working on new calibrations or not, but did overhear the trans tech tell the manager that at least two other V-6's had similar concerns. Got the usual "doesn't harm anything, doesn't affect the vehicle" story. Maybe I'm wrong, but it would seem the shudder would come more under high load than low load. Maybe under high load the lock up is delayed and the engine turning enough rpm's to eliminate the shudder? Any thought's?
 
Second question - The official Chevy Silverado site ( as well as a couple of others) appears to indicate that the 1500 as standard equipment has a trans. cooler. The HD with tow has an "aux trans cooler". Does the base 1500 have a trans cooler? If so, what the heck is the difference between the two? I certainly can't seem to find one if there really is one?
 
It was sort of ironic given the many posts that when I mentioned a vibration problem and before the Ser/ Mgr saw the truck his immediate response was "yea those Silverado's have a vibration problem at high speeds". Retracted it when he saw it was a 2001. Guess at least this dealer has had his share of shakerado problems.

$687.54 sounds like a lot of money for 4 tires. At tirerack.com I got 4 Yokohama Geolander HT 255/70SR16 tires and 4 new Chevrolet OEM Alloy wheel factory takeoffs, mounted and balanced including shipping for $598.91. If you have the steel wheels and what to upgrade to the alloys this is a good way to do it as the new alloy takeoffs are only $59 a piece. I ordered them on a Friday and they were delivered on the next Wednesday. If you don't want the wheels the tires were $75/each. Another internet place to check is discounttiredirect.com, their prices are about the same as tirerack, but their shipping was less, the reason I went with tirerack is because I wanted to upgrade to the alloy wheels, and discounttiredirect didn't have them. They guarantee their balance, and when I got mine I took them to Goodyear to get their lifetime rotation and balance maintenance contract and they were all out of balance. I called tirerack and told them this and they had me fax them the bill and gave me a full refund for the Goodyear bill, so I ended up with a lifetime rotation and balance for free.
Shop around before you buy those tires.

#1943 of 6769 Transmission coolers by blacksilver

All Silv automatic tranny's have a "sort of" transmission cooler which is just a few turns of tubing immersed in the regular radiator coolant tank.
 
When you buy the towing pkg you get an additional separate "radiator" which is connected in series with the cooling tubes and mounted in front of the engine-cooling radiator.

john...before progressing with your tire purchase, click here.
 
don't mess with paying full price if you had firestone's come standard on your truck. print the above letter, take it to your firestone dealer, and they will give you new bridgestone duelers for the difference in residual value of the firestones you have and the price of the new tires. i did this and got 6-ply b-stone dueler at's for $290 installed, free lifetime rotation/balance, and road hazard warranty. of course, i had 12k miles on my old f-stones when i did this. to figure residual value of your existing f-stones, they will simply measure your current tread depth as compared to when new. whatever percentage of tread you have remaining is the percentage of "new cost" they will credit you against your new tires.
 
if you want to see what they look like mounted, check out my pictrail site by clicking here.
 
good luck

I looked at those Dueler M/Ts on tirerack, they were $133/ea. I question why you would want to put those on a 2WD 6 cylinder truck, those tires are meant for hardcore off-roading. I would think that those big heavy tires would have a negative affect on your gas mileage, and can guarantee your highway ride would be a lot rougher. Additionally, you're spending a lot more money for those tires than you would for the type of tires you should be putting on a 2 WD truck. If your truck came with 235/75R16s like mine, the 245/75R16 will also throw off your speedometer readings a little bit, the 255/70R16s are a perfect match to the height of the 235/75R16s. If you want a more offraod type of tire that will still give you a smooth highway ride and would not affect your gas mileage, I'd recommend the Dunlop Radial Rover A/Ts, 255/70R16, they are only $76 at discounttiredirect.com, have a 60,000 mile treadwear guarantee, and have the highest tire quality rating (500AB) I've seen for a truck tire. I kind of wish I had gone with the Dunlops. Save yourself some money and some headaches and get a tire more appropriate for your type of truck.

I agree with kansan. Those tires are a total mismatch to your truck.

#1948 of 6769 thanks kansan,bco,&blacksilver by john294

Mar 08, 2001 (7:21 pm)

I did a bit of research on those MTs and I must agree with you all that they are a bit too much for my V6 even if it is a 4x4,I liked the way they looked but dont want to give up performance for looks.I have factory Goodyear wrangler ST 245/75r16 tires and was looking for something to do some beach driving at Nags Head Va this summer, we didnt get much snow this year so I didnt get to use the 4x4 much .The ATs look good bco you think they can handle the beach?My friends say to just let some air out of the wranglers and go for it.. ?????

No, I don't think it's your truck. What you're describing sounds like a V6 in a 4300 lb. truck. You can't compare the taurus and the grand am, which at best would be described as midsize to a fullsize pickup. Weight and wind resistance will definitely slow the truck down and add drag on the V6.
 
About a year and a half ago, someone posted the same thing with the transmission, can't remember why it did that.
