Default 4l60e gone bad???

just bought car 3 weeks ago, took out today and the car was doing fine. 1-2 shift did fine, then 2-3 shift seemed a little slow and seemed to slip. almost half a mile or so i had to stop again for a turning car. same thing 1-2 shifts where good but this time 2-3 shift went completly out. slowed down some tried to go again but it was just building rpms and then started to slip bad and seemed to get worse so i stopped the car.

99 camaro z28 4l60e w/ 103,000mi- car is bone stock no aftermarket parts what so ever

checked fluid- full, recent filter change

not likely, flush is not a "fix all" as many people think, if you have some problems to begin with, a flush can actually cause more damage.

But if a flush hasn't been done that could likely be a problem. When you did the filter change did you find any material in you fluid?

BTW filter change is a waste of money, if your gonna change the filter do a flush at the same time, its like me draining two quarts of engine oil changing the oil filter and topping it off and saying I did an oil change.

Yeah if it's slipping a fluid change probably won't help anything. But worth a try if it's on it's last leg.

Someone probably dumped some friction modifier in there so they could sell it.

never doing a flush will not cause a problem, but you SHOULD change the fluid (yes there is a difference) and if you have metal shavings in your trans fluid, and it gets caught in the filter you will burn your transmission up in a heart beat. its not a waste of time to change the filter. but if its already slipping, he needs to get it checked out its not likely a small issue that can be fixed with new fluid/filter.

not changing the fluid will not cause a problem???????!!?!!?!?!
thats how we get most of our tranny work.

its waste of time to JUST change the filter, like I stated with my oil change scenario its the same thing, doing a tranny flush is maintenance on most cars (except BMWs and others) every 50k you should do a flush, I was suggesting a cheap alternative, if it works great if not its no big deal, then you know you need a tranny that way you dont have to pay for a diagnosis, probably cost about the same or less for a flush, if he does it himself

thats not what i said, changing the fluid is necessary, flushing is not, its different, you dont "flush" your oil when you change it, but it still needs to be changed. a flush is never necessary, and in many cases has caused problems.

Don't bother changing the fluid at all... Changing the trans fluid on a trans that is slipping really bad would be like changing the oil on an engine with a spun bearing in hopes of fixing it. Just save the money on on the fluid and get a new trans.

and what about the oil in the tourque converter? Most of the tranny fliud isnt in the pan it cycles through the tranny, your only changing a couple mabye three quarts when you just take out the pan and change the filter, what about the other four or five quarts.

If I take out a radiator hose I am not draining all the coolant out of it unless I run it till its clean, its the same concept.



To me its worth a try and if you dont want to thats fine too, and yes the 4l60e suck *** thats just one more reason why I did the a4 to m6 swap.

406malibu if you have any autos dont just change the filter, I am trying to help you guys out, my dad has been doing mechanics for over 30 years and my bro has been doing it for more than 10years, I am still learning but I know about this.

In your case I may be your tranny is bad but to me its worth a try if you know how to do a flush, just my two cents.

no need to help me out, my dads been working on transmissions since he was 15, and my parents own a transmission shop. I've grown up around it, and have even done a few myself. I dont claim to know everything about it, but i do know a flush is not a cure all.
