96 Monte Carlo 3.1 transmission was shifting fine then got up to go to work and no overdrive. I changed the fluid and filter nothing changed. Can someone please help?

 

Welcome to the forum.
Thanks for Joining the MCF Family

Is the trans full? ... Is it overfull?

How many miles are on it? Most timesthese trans hit around 80,000 + miles
and trans issues start to show up....It could also be something as simple as a shift solenoid.

Maybe some one else will chime in with more ideas/suggestions...

 

When I'm on the highway doing 60 my rpms are at around 4000

 

Just under 160000 fluid is full did see some shavings in the pan and tiny chunks not just real fine metal

 

How long ago did u do the fluid filter change? (what mileage?)

But with 160,000 + miles on it....

My best guess..... Its time to get it rebuilt....

 

Just got the car a month ago been driving fine until this and changed the filter this past friday

 

Maybe try pulling the pan... Change out the solenoid?.... If that doesn't help..
Then I would recommend a soft rebuild..... or get a used trans....and hope its better than the one you have?

 

If the tranny is bad how long would it take to swap it out? I do have experience and I have swapped fwd trans before just not in one of these Monte carlos

 

Another thing when I'm on the interstate and my rpms are at around 4g I let off the gas my rpms go down to idle then I press the gas to speed up it doesn't catch until I'm back up to 4gs and it does that in all gears like it is slipping I guess

 

Had the same issue with my '01. Splines on the OD shaft were gone so it couldn't lock into OD. Replaced it and it's back to around 2,000 rpm's at 70mph.
