OT Mechanics: Transmission Fluid replacement
Posted on 1/25/14 at 9:49 pm
Posted on 1/25/14 at 9:49 pm
I have a suburban that has 102k miles and I pull a camper with it. I have heard conflicting reports on transmission fluid changes. Is this something that can and should be changed like the oil or is it more complicated?

Both.
You have to drop the pan and change the filter too.
But it should be done.

Not difficult. Look for youtube videos and they'll walk you right thru it. Make sure you replace the filter as well as the fluid.

You'd have to get it done. You aren't gonna be able to flush the whole system on those by yourself IIRC. I'd do it, but wouldn't go synthetic

Have is it been changed before? That will determine what you should do
If it hasn't been done before.. I'd just drain and refill. Don't flush or you're asking to have tranny issues.

If you've never changed the fluid, don't.
The filter does need to be replaced though.

If it's never been done before, I would be a little hesitant. You can have a complete flush done, which removes all the fluid, and replaces it with new. I would change the filter as well. With 100k, could get tricky, prepare yourself for a new tranny.

i bought it with 70k miles, so i know I have not done it in at least 30k. I am getting ready to tow the camper to disney world...so i may hold off till after the trip. Hate to screw up the tranny now.

Like mentioned, prob best to not flush and replace filter with a drain/fill.
I know many people who never replace it.

Some atf fluids are only synthetic

Jesus Christ, changing the fluid and filter won't destroy a tranny.

Drain the fluid, which will only remove 3 or 4 qts. The rest is held up in the torque convertor. I change my tranny fluid every 20,000 miles. Whatever you do, DO NOT FLUSH!!

True.. If your transmission was going to go out anyway a transmission fluid change won't hurt or help it. Best bet, like others have said is to just change the fluid. If you are towing I would add a stacked fin cooler in front of the radiator if it doesn't already have one. I also would add a magnafine(sp) in line filter. Both products should cost you under $100. Add in the OEM filter and some transmission fluid and you'll have a full service and extra reliability for under $200.
I did this exact service to a 1996 Dodge minivan and I got 120k off a rebuilt transmission. 220k total as I sold it at 220k, and the tranny was running fine at the time of sale.

I've heard that you shouldn't flush as well. We had our Honda Odyssey (120k miles) flushed and about 10,000 miles later, our transmission started missing gears during acceleration. I've heard it removes the seals created by debris around the gaskets when you do a complete flush.

wrong
trans fluid is high in dstergents and if you havent changed the fluid regularly it will break particles loose and kill trans

If the fluid is really bad off and you must change it, I recommend adding a bottle of Lucas oil Transmission fix.

No... no. A thousand times no.
No Lucas snake oil products.
Pull the pan, change the filter. Replace pan. Refill with almost same amount that you drained.
Start engine, set brake. Shift to low. Then back up to park.
Check fluid level, add if needed.
Go drive and get up to operating temps, stop, wait five. Check again with engine running. Add if need be
Do a drain and fill once a year or 15k miles.
As for the Honda Guy...Honda's auto trans are notorious for grenading well before their time.

If you can afford going to Disney with the kids, just take it to a car shop, pay for someone to handle it for you whichever way is correct, and quit worrying about it.
