Transmission after 110k miles

Hey just joined this site looking for some help with 2015 Tundra Sr5. It has 116k miles and due for trans flush, but I was speaking with someone from an auto shop and was told a a trans flush after 100-110k miles could cause the transmission to lock up. In other words, I was told if I’m not having any issues with the transmission after 100kmiles don’t change the fluid. Has anyone else heard this before? Thank yall in advance

 

Heard it many times - I think if probs are gonna start after a trans flush its because the problems were going to start.

So lets assume you have an otherwise good trans - I would suggest just what Toyota suggests - do a drain/fill only for now. Then perhaps every 5 motor oil changes do another trans drain/fill. This way it will always have fresh fluid and some of the 'old' to help it along with.

Don't worry about the 'filter' if it is running fine otherwise - its more like a strainer for really large chunks (when its really too far gone anyway). Do use a full synthetic fluid for maximum life out of it. Luck and enjoy the rig.

 

If you’re not having any shifting issues (slipping, misses, hesitations…etc) I’d let it ride. At the most, like Johnsonman said, you could just do a drain and fill.

 

Drain and fill, drive a day, do another, repeat as many times as you want to feel more fresh

 

It's important that you (and your auto repair shop) make the distinction between "Drain and Fill" vs a "vacuum-induced flush" where there is the possibility of re-introducing some bits and pieces that have settled and currently aren't causing problems, into some areas where they will cause problems.
The drain and fill method isn't prone to this "phenomenon" and is generally a good idea at regular intervals as the other members in this thread have suggested.

 

Ditto on simple drain and fill.....never a flush.

 

Agreed with above suggesting drain and fill.

Here's a good how-to video:

^^^ What they've already said ^^^

Do a drain and fill now; drive it for 15k or so; do another; drive it another 15k or so; do another... and at that point you'll have exchanged most of the fluid and the trans will be happy w/you.

Also, don't forget to change other fluids as well if they haven't been done...

Differentials and transfer case about every 30k

Coolant every 50k or 5 years (use OE Pink 50/50 Super Long Life)

Brake Fluid every 3-5 years (drain and fill only not flush) brake fluid is hydroscopic and will take on water over time and reduce the boiling point of the fluid

Power Steering Fluid every 50-70k (do not use trans fluid as some do)

Spark plugs at about 120k (use OE only)

That should do it for your maintenance list

 

Can you clarify this? I used Dex III ATF as the cap on the PS reservoir states to do, and I've read everyone tends to do the same on here

 

Toyota has power steering fluid specifically.

 

What he said ^^^

 

Yall are great! Exactly the info I was looking for. Much appreciated!!!

 

Do you need any special tools for "drain and fill"? Or is it just the drain bolt and fill from top?

 

Watch the video linked above in post #7. All you'll need is a socket/ratchet for the drain, fill, and check plugs, as well as a way of getting fluid into the fill plug on the side of the transmission (I'd suggest about 3ft of 1/2" ID clear tubing).

The video explains the whole process and makes it easy to follow along

 

Thank you

 

Oh almost forgot you'll actually need a small Allen wrench for the check plug, that ones not a typical hex head bolt/nut

 

Just be careful on the check plug because of the 5mm hex - it's easy to strip out. Why they didn't use a normal bolt head like the drain plug, I don't know.

 

Good point. I know all too well how easy allen head bolts are to strip out. Can't believe Toyota still uses them instead of perfectly good hex head bolts
