#253 of 2018 Go with the 4.3!
Sep 17, 2002 (6:27 am)
If you are buying it to be a truck (hauling or towing) the the 2.2 shouldn't even be considered. GM puts the 2.2 in that truck for basically four reasons. One, it helps raise their CAFE, Corporate Average Fuel Economy, which is closely monitored by the EPA bureaucrats. Two, it helps it compete with the four-banger Ranger and Japanese trucks, often advertised as price leaders to get you into the dealership, where they will try to sell you a V-6 or V-8 truck. Three, they sell alot of them to rental car companies and fleets that only use the trucks for light delivery. If you own and operate 500 trucks, a difference in 3-4 MPG makes a huge dent in your budget. Fourth, if the Chevy Cavalier and other lines that use the 2.2 engine are not selling well, GM can easily modify their production line to make the 2.2 engine in a truck configuration (different oil pan and other minor modifications)
I have the 4.3 in my 2000 S-10 extended cab. Reliable, quiet, never stalls, quits, runs hot or idles rough. It tows and hauls well. It easily breaks the tires loose if I want to, and always 'runs with the big dogs.'
Based upon comments from owners with the 4.3 engine in the "Older S-10" discussion, this engine easily lasts well over 150K. I'm tired of car payments, so when mine is paid off, I hope to break 300K on synthetic oil before I have to buy another one.
#254 of 2018 Automatic Transmision Upshift Clunk
Sep 30, 2002 (5:24 pm)
I have a 2002 Ext Cab 4wd S10 with 9000 miles on it. There is a noticeable clunk when the transmission upshifts from 2nd to 3rd, especially when accelerating slowly. I have checked all the posts on this board and haven't seen any mention of this. There is a TSB out on this, number 01-07-30-042, but being a consumer I can't find the details for it. Does anyone know anything about this problem? Thanks!

Information on 2-3 Upshift Clunk Noise
2002 and Prior Light Duty Trucks
Equipped with 4L60E Automatic Transmission
Some vehicles may exhibit a clunk noise that can be heard on a 2-3 upshift.
During a 2-3 upshift, the 2-4 band is released and the 3-4 clutch is applied. The timing of this shift can cause a momentary torque reversal of the output shaft that results in a clunk noise. This condition may be worse on a 4-wheel drive vehicle due to the additional tolerances in the transfer case.
This is a normal condition. No repairs should be attempted.

Thanks for the info Joe! That is kind of what I suspected (that the noise was "normal") because my '98 Blazer had a similar noise but I never got it checked out. It's still discouraging to pay $25K for a truck and have it "clunk" when it shifts. I am a long time GM guy but am seriously considering trying something else next time. GM seems to be caring less about the details these days. I have a restored '57 Chevy Bel Air and it is still going strong! I only wish my S10 would last half as long! Thanks again!

I have a 99 Sonoma 4L60E 2 wd and no clunk,whats up.
#258 of 2018 4.3 intake gaskets
Oct 11, 2002 (6:18 pm)
I just had to have the intake gaskets replaced on my 99 4.3 S-10 due to an external antifreeze leak. The truck only has 33,000 miles on it. The dealer did however cover it 100% even though it will be 4 years old in November.
#259 of 2018 4.3 eng knock under load
Oct 31, 2002 (8:05 am)
Wish I'd found this site earlier. My problem is with my 92 S10 4.3 auto/trans (188,000). When I start out from a light I get a pretty bad knock noise from the engine. The problem is even worse when towing my boat. I've tried just about everything except tearing into the guts of it. I've replaced timing set, w/pump, (2)mtr mounts, cat converter, O2 sensor, and ign module with no fix. My previous 89 S10 4.3 had none of these problems and would tow the boat up/down without so much as a whisper and ran great with over 230K until it tried to go through a minivan.
#260 of 2018 99 S-10 Electrical Problem 2.2L 5-speed
Nov 10, 2002 (8:57 am)
Well, about a year ago, I bought the '99 s-10 truck at a good price, with low miles, and until now, I have been really satisfied with everything. The past couple of days, I have been experiencing problems. The problem seems to be an electrical problem, where the computer(maybe?) is cutting out. When I start to take off after warming it up, all the gauges start to jump, the idiot lights flicker, and then the truck stalls. This happened several times in a row, before it started to run fine again. It ran fine for an entire day before it happened again, and it really worries me. I asked some other people about it, and they say it could be a computer control module. The truck only has 43,800 miles on it, and this shouldn't be happening with so little miles.
#261 of 2018 first thing
Nov 10, 2002 (9:52 am)
to do is check the battery connections,at the battery & at the engine.
Nov 11, 2002 (9:10 am)
I already checked the connections. That isn't a problem. I talked to more people about my problem. My future wife's father works for GM, and he said that they discovered a problem with a computer module, and that they thought they were going to have to replace them. He told me that reseting the computer fixes the problem. I did that yesterday, and I haven't had the problem since.
