Hello All,
this is my second seek for help post in here, 1st was fuel pump relay blowing off fuse 28 pcm1
you can see it here https://gmtnation.com/forums/threads/fuse-28-pcm1-keeps-blowing.19367/
thanks to mooseman and all the crew who helped me a lot !!
ok so i am the third owner of a this 2002 TB LS, only 110K miles on it,
but the tranny is start to act up, most of the time the problem starts with a cool engine on the mornings
The symptom is: delayed hard shifting from 1st gear to 2nd gear, then sometime it refuse to switch to 3rd gear
so i canot rev up more than 3k RPM's and that its about 33MPH speed, but after a couple of minutes
it starts to shift normal trough all the 4 gears
as a side notes, when stooping on a red light it shifts down perfect, problem is up shifting not downshifting ,the fluid level is normal
i read somewhere that maybe the solenoids are giving up, so to add a quart of TRANSX additive, and if the problem do not go in 2 days, you need to overhaul the tranny.
so if you guys think i need to add the transX thing, how do i remove a quart of fluid from the tranny?
also, can i do a filter change and pan clean along with the magnet on the pan who attracts all the worn out metal
debri, i saw a you tube video and like black gunk
Fluid is Dexroon III or VI (synthetic)
what do you guys recommend to do at this point
Oh, i forgto to add, when i experience the hard shift problem, i hear a heavy fan ( radiator ) roar like if the fan clutch its stuck and the fan rotates at higher rpm, the more i RPM the engine the more the fan roar, then after a couple of minutes it goes to silent operation, i do not know if one thing is linked to the other, or is just coincidence, but murphy law says that says "whatever can go wrong, will go wrong. "
Thanks
Rolo.
