Transmission may now be toast since you continued to drive it when maybe low on fluid or torque converter had failed. How long since last fluid and filter change? Ever?

that is a hum dinger, largest ever posted, in one shot.
very good.!
one word , the transmission slips. (never drive a slipping tranny)
overheat indicator.! that is key.
many newer cars will change the transmission shifting any time
the engine over heats.
and overheat wins over transmission , every time.
if the engine burns up, what good is any transmission.? nada.

solve overheat first.

slip or flare.
is when the engine RPM rises fast and the car dont go faster.
SLIPS.
and slipping burns up trannyclutchs and increases the damage. inside the transmission, dont do that. dont allow it,
park it and fix it.

on some tranny there is a temperature sensor that the TCM
watches and changes shift patterns based on AFT fluid temps.
and if the ATF fluid gets too hot , it takes actions. to keep the tranny from harm.

why not get a scan too and see what DTC errors there are..
DTC, engine overheate.
DTC< tranny overheat (caused by above)

put transmission shifter in D2 drive it so you feel the second gear on. then stop the car did he down shift .

I had the same problem. these trailblazer are a pain. There is a cable that runs underneath the vehicle, and that is probably the problem. The cable is broke.

try disconnecting cable to transmission turn the shifter on transmission manually down there connect cable again start car try it if not try it again turn once then connect cable again then try it if not the transmission is not good

check transmission fluid level- run/drive for about 10 min. , park car- check with engine running- add fluid if needed- ,if fluid NOT low- transmission filter needs to be changed

It is about $ 2000.00 car $500.00???Check level oil, did ever change oil?Last thing you can add Lucas no slip up to 3 bottle.

call a mobile mechanic to have a look easiest way for this is hands on ,sounds like low on transmission fluid but i could be wrong
