Question about 1996 Chevrolet Blazer

3 Answers

I have a 1997 chevrolet Z71 with a 350 vortec engine which has 207,000 miles on it. I've been having problems with my engine. First of all I had a new "black box" transmission installed last year because it was "slipping" bad. Anyways, when I crank it up, it idles fine and when I press the gas, it revs up fine. When I put in in gear, It's like your riding the clutch on a standard shift truck. I have to press it half way to the floor for it to take off. Also, when I get going down the road and I accelerate as if I were going to pass someone, it will rev up and slowly catch. Again, it's like your riding the clutch on a stick shift. I had the mechanic that installed my transmission recheck it and he said it was fine. But he did say something about bad compression on one of the valves. What does this sound like to you? Do I need to install a new engine? Please help me, I'm just about out of options...

    Im not sure if the converter was replaced or not. I agree with you too. The engine idles and cranks fine. There are no knocking or pinging noises either. I had the mechanic recheck the trans. just before the warranty ran out. But, I'm goning to take it back to him. What questions do I need to ask him as far as what he needs to check?

Sounds like the transmission repair man is trying to get rid of you until the warranty is up...its close isnt it ? ...he would have not said it was your engine and definatly knows that your engine wouldnt make your transmission slip...i would take it somewhere else and have it diagnosed before the warranty goes out and bring the results to the man that lied about your engine being the problem.he is definatly trying to stick it to you...get this documented by a pro and bring it back for repair and demand that he sticks to his warranty or if you go too many miles like he hopes you do then it will be too late...i would also let him know that he tried to stick it to you if it ends up being the transmission...but from what you are saying it is....Could be low fluid, or could be the filter and low fluid.,or could be converter...or a combo of the above including also sencors? A transmission has about 2000 parts and from experience would NEVER have one rebuilt...i havent seen one that has ever held up in the long run....You would come out better in my opinion getting one with low miles out of a salvage yard, because they will be factory built transmissions and not rebuilt by a mechanic...there are some very good mechanics , but no one can build a transmission like the factory.and one out of a salvaged vehicle has always been a very good choice and is even 2 times as cheap...especially if you can install it yourself...

To me it sounds like the trannie fluid is low or needing changed. But if the compression is off its off i wouldn't think it would effect the uptake of the transmission though.
is he under warranty still? its definately a transmission problem i would say. low fluid or old fluid i would check/replace fluid first to rule it out if it still does it you will need to open it up and check the convertor etc. Did he replace this when he changed the transmission?

    i would ask him to check the fluid level as the transmission needs to have the correct amount of fluid to have enough pressure which is why when you raise the rpm the pressure rises and you get moving. Ask him if the convertor was replaced, check your receipts also to see if he charged you for one. 
    Get things like the fluid changed see if it helps and while its getting changed add an addidtive to it to prevent the excessive slipping.


    Without having the truck infront of me its hard to diagnose.


    Hope this helps.

That is transmission all the way.Sounds like slippage of the bands or pressure leaking past the clutches. A bad engine valve or low compression in one cykinder would cause the engine to run rough. Especially at idle. Check the transmission fluid. It should be nice and red. If it has a burnt smell. Something is up. Don't confuse a strong chemical smell with a burnt smell. The newer fluids have a strong chemical to them. This is normal.

    I would get somone to pull the pan and see what is on the bottom. I suspect it will be quite mucky.What you find will tell the story.Fine bits of sandy looking material indicates band or clutch problems.Metal in the pan is a sign of heavy wear. Most pans have a magnet to catch filings of steel and iron. Check that carefuly too.The location of the piles of material can sometimes help to locate problem parts as many times the material will pile up right under the affected component/components.

97 k1500 5.7 liter vortec misses on cylinders 3 and 5 while idling. about 1500 rpm only cylinder 3 and 4 miss then at 2000 rpm only cylinder 4 and 8 miss. what could cause this?


I have had continuous missing issues on my 1997 Silverado after i had a new engine installed 30,000 miles ago. Today I purchased a new gasket for the EGR Valve and removed it. The mechanic had re-used the old gasket when he replaced the engine and cut corners to save $2.00. I found he had installed the EGR bass-ackwards causing my check engine light to stay on and the engine always to miss. Engine runs GREAT now
