I could be just acting paranoid after my brother dropped $3,000 into his transmission on his 2002 blazer at 106k but, I feel I may have something going on with my tranny now. I have a 1997 Chevy blazer 4.3 with famous 4L60E transmission. I am not positive but I feel the previous owner had it rebuilt at some point in time. It shifts way to well and solid and the fluid was clean when I bought it 4 years ago with 122k. Now my blazer has 148k and I changed the fluid, filter and gasket on the tranny about 2 years ago and replaced both solenoids because I broke them when dropping the pan. I also flushed out the torque converter too.
Now after I have been running my blazer for a while and it heats up, reverse feels a little weak on a steep hill and in get a light metal clicking sound on acceleration in reverse on steep inclines. I also notice this metal clicking sound when pulling out in drive on an incline or when pulling out fast in drive too. I recently replaced both bad motor mound and tranny mount thinking that way it but, the noise is still there. It doesn’t sound horrible. It’s like metal is being torqued and its clicking/creaking. It does have 4 wheel drive but it does it in 2 wheel drive too. I was something drive shaft related but the universals seem ok. I also replaced the front cv axels and inner seals too. The tranny fluid looks pink still and smells fine with no bubbles. There is some black friction material on the rag when I wipe it but nothin serious. All the other gears feels and sound strong when driving.
Has anyone else experienced this? Think it’s ok and just getting old? I know these trannys are know for the sun shell gear to go that makes reverse go and second and over drive to be weak or fail too. I know from experience how bad the transmission sounds even at idle when that happens and I’m not getting anyone of that. Maybe it’s at the beginning stages?
