My brother recently got a 1999 Chevy Blazer with the 4.3 V6 and 4 speed auto with 234K miles. Just yesterday when driving on the highway the transmission began slipping. He told me it was slipping from 2nd to 3rd, and from 3rd to 4th. He also mentioned that it didn't start right away, it wasn't until being on the highway for a while that it started slipping. Once he reached his destination it sat for a couple of hours then upon returning the same thing happened. No slipping at first then slipping after driving for a while. So maybe it has to do with the thinning of the fluid as it heats up? I don't know. Anyway, I checked the fluid last night at its brown and does not smell fresh. Its not black and doesn't smell like burned toast or anything but it definitely needs to be changed. He is taking it in tomorrow to have it looked at and possibly change the fluid and filter if the shop thinks that is in order.
I know 234K miles is a lot of miles but he has been in this car many times before taking ownership and it didn't exhibit these signs until now. Is there a good chance that a fluid and filter change will rectify the issue? Either way, I will updated tomorrow if he finds something out.
