Old Transmission Oil
Been having issues lately on the truck, surging issues etc...
For now my concern is the transmission.
I had checked it recently to find it has discoloration (darker red to off blackish) and smells bad!
2001 1500, 190k miles, bought the truck at about 140k miles so II am not sure if the previous owner changed the fluid on regular intervals.
I fear changing the fluid due to the old saying it drops the tranny shortly after the service.
Now I have read on here in the course of searching the issue that flushing can be bad for it, and just change the fluid a couple times in the course of a couple weeks and it should be ok and hope for the best.
What I'm hoping to find out is, is that true, or are there precautionary measures I can take to prevent that from happening? Should I have it flushed or just fluid and filters changed out?
Has anyone dealt with high mileage/old oil and changed the oil in the tranny without any issues shortly after or at all?
I believe my tranny started cooking some oil with the surging going on for some time now and I may have a handle on that issue at this point. Hopefully the tranny is not too far past the point.
Thanks

Personally, when I buy any used vehicle/machine, I immeadiately have all fluids serviced suspecting the previous owner did not maintain things the way I do. It is peice of mindfor which the cost is built into my purchase price vs. what the sellers price is. Good luck.

RE: Old Transmission Oil
That method worked for me 4 changes or a course of two weeks.. I bought a work truck from my dad about 100000 miles ago.. It has 239000 now.. He had never changed the tranny fluid and really i think I can count the oil changes on one hand.. the tranny fluid was black and really reaked.. I changed it with cheap atf+4 and a good filter.. (monday) then friday changed it again with somemore cheapo stuff. (Saturday) Then tuesday came a around did a fluid change and filter.. Then Saturday came again and the fluid was red so i swaped it out again with some ATF+4 and a Mopar filter from my local stealership.. Like I said it was bad.. depending on how bads urs is I would change it untill it is red.. theres a lot of detergents in the fluid so it will nockthe crap lose just make sure to use a good filter.. both times.. Then whenyou put the good fluid in on your last change change the filter again just for good measure.. make sure you cahnge it until it is consitanly red and you wll be good.

So then the transmission flush at a shop is not a good way to go?
If I am to do the change it a few times method, sounds like it will have to wait til it's at least a little warmer out, few weeks hopefully.
My fluid is not black black, more like an off red off black. I just wanted to basically check the level when I noticed it, but also too, the oil level was pretty high, over the max level!
Didn't seem foamy or anything, just seemed overfilled. Maybe that gave me the slipping sensation?
I really hope it lasts til its a little warm out.
I happened to notice "Sea Foam Tranny Cleaner" in the local Auto Zone. I didn't read it, I am skeptical about putting stuff in the trans......anyone ever hear of it or use it with sucess?

Never heard of it.. if it is seafoam brand prolly a good buy but dont take that to the grave I would read reviews. Mine works great and now I change it every 20k in my work truck and 30k in my personal truck. I wouldnt flush it though.. Unless it is a dealer job.. They f*** it up normally you can persue it and have it fixed.Local shops arent backed by the brand.

I have also heard that changing the fluid on a hi mileage tranny will cause it to go bad. Let us know what happens, please.
Also, per the owners manual and service manual the fluid levelMUST be checked with tranny in NEUTRAL.And engine running, parking brake on and wheel chocks.

Well I have no choice, I have alot of work to do on the truck, but sections at a time.
I certainly will keep this post updated as time goes by.

RE: Old Transmission Oil
Ive had mine flushed.. I think it was 70k when I Had it done... Mines still going strong.. but thats alot less miles than yours... I have 93k now...
My truck never had the fluid or filter changed prior to this... with the flush they DIDNOT replace the filter, so my truck still has the origonal tranny filter in it now... This spring when it warms up im planning on changing it and adjsuting the bands.
