Transmission fluid changes for 4t60E
Just wondering how religious some of you are out there with trans fluid changes...Or maybe not so religious? I have 66k on my 91 ETC. Trans is shifting SUPERBLY. Shifts as smooth as a hot knife through butter and virtually seamless....But i wonder about the condition of fluid. Its not the nice Magenta color but a light brown almost identical to clean motor oil. No burnt smell, In fact, smells the same as new fluid.
One might suggest to change it...But i am one who is hung up on all the transmission myths out there. One being if its working fine leave it be. I think i am spooked by two incidents in my trans. fluid change history. Changed fluid on a 1975 Mercury Cougar i had way back when at about 96K miles.....Next few days following, Trans. started slipping. Buddy of mine changed fluid on his 91 Lincoln LSC at higher miles...within a few days...trans slipped as well. Coincidence maybe.
As much is argued about flushes as well, But i think a fluid change by pan drop and filter change the best way. Just looking for thoughts
Right. Owner neglects transmission (or it just gets old), transmission starts acting up, owner has fluid changed to try and fix the proem. Transmission eventually fails, and the owner blames the fluid change.
FLUSHING is another story. Pressurized fluid stirring up sediment that wasn't doing any harm and/or junk from the last car that was hooked up to the machine can kill a transmission in a hurry.
The myth is that draining and filling with clean fluid will damage the transmission in any way.
