My trailblazer won't shift. It just revs up like its in neutral. I changed transmission fluid and filter. I changed shift solenoids. New thermostat. It has 140000 miles on it. Anyone else having issues like this?

gmcman said:When did you change the trans fluid?
Did you check the trans fluid level when hot, level ground, engine running?
Did you ever drive it with low fluid and notice it slipping?
If you have a Reduced Engine Power light, did you try to restart it?
Does it drive away from a stop weak or strong then not shift?
What exactly did you do when you dropped the pan?
Could be low on fluid, starving of fluid, did this happen all of a sudden or over a short period of time?
They all work. 3 gear can't get above 10.STLtrailbSS said:Tried to go to 1,2,3 gears yet or just D?
STLtrailbSS said:10mph is such a weird area for it to stop, when my trannys legitimately Broke I would be stuck in a gear redlining but why 10mph?? and you have no drivetrain codes or ANYTHING? My transmission knowledge is "take it to the shop" but I have not heard a problem like yours

Why did you change the shift solenoids? Did you have an error code pointing to them? Did they test outside of acceptable resistance? Are you sure you reconnected them properly?
Can you really wind it up in first (I'm talking floor it until it hits ~40 mph) and get it to skip over second and go to third gear? You'll need the selector in "3". If it doesn't have to do with the shift solenoids, you have probably either burned up your second clutch, destroyed the band/it isn't holding the input drum, or broken your sunshell. Go to a transmission shop unless you are very, very mechanically inclined. Or get a used transmission.
gmcman said:I believe the shift solenoids have their connectors wired in such a way it's hard to get them reversed, but it's possible. First thing is to stop driving it before you smoke a clutch pack. You need to pull the pan again and see what's going on.
What code did you get?
Did you get a deep pan filter?
Are the shift solenoid harnesses the only ones you removed? Did you reverse the connections.? Are the solenoids from the dealer?
Are you absolutely sure you fully seated the shift solenoids?
Did you get the spring clip back in for both solenoids? Check again?
Did you leave the old filter seal alone or replace it?
Are you checking both sides of the dipstick? Use the lower reading.
The trans will start from a stop in 1st gear in 1,3,D.....it will start in 2nd when in "2" if you keep the accel pedal below WOT.
Once you have ensured everything else is correct, try starting in 2nd...if it won't move then that could be bad. Hopefully you just have a screwy solenoid and didn't fry a clutch pack.
Just a tip, anyone who gets into a situation where the trans doesn't feel right or won't shift, don't rev it up or try to drive it. Sometimes it's just low fluid, faulty solenoid, maybe something simple....but a partially engaged clutch from low pressure will burn up real quick if allowed to slip, then it's a 4-digit repair bill.
