2006 DC transmission fluid change?

So my new to me Tundra has very few maintenance records. I’m getting the t-belt, WP, and suck done next week. I’d like to go ahead and change the transmission fluid. Is just a drain and fill the recommended procedure? My wife has a 02 Sequioa, and I have the seller tossed in the printed factory workshop manuals. I know the transmission is different between the two but is the procedure fairly the same?

Oil changes were kept up with and isn’t due for another 1500 miles. Tires will be rotated. What else am I missing?

thanks

 

Your truck has a harder process than an earlier model. Your truck has no dipstick for the trans. You have to drain fluid into a container where you can measure the amount (temperature controlled too) and pour that amount of new fluid in.

 

Thanks. I knew it couldn’t be that I was lucky enough for them to be the same. I do some research on the process.

No better place to do your research than the 05-06 Toyota Tundra Factory Service Manual found in the link below.

Yardbird-very cool. I’ve dealt with sealed transmissions before, although I don’t recall any having a check valve like the one in the video.

weadjust- awesome! Thank you.

 

In the absence of past records on transmission service, I would suggest you consider dropping the pan, replacing the filter and having the transmission valve body re-torqued. My auto service company charged $220 to have this done on my 05 DC 2 years ago, and I have had this service performed every 50K miles since I’ve owned the vehicle brand new. Breakdown was labor, $136; pan gasket, $12; AT filter $32; and 4.5 qts Toyota WS ATF fluid, $43. They also cut open the old filter and inspect it to let me know if there are any signs of abnormal transmission wear I need to aware of.

 

It's a sealed trans. I just had my 05 done at the dealer at 100k miles per FSM maintenance schedule. It's a flush process and they use some cleaner and conditioner as well. I would usually do trans flushes myself but the sealed trans process gave me hesitation. Better left to the pros, plus I had a coupon. Good for another 100k now.

 

I just need to get the stupid sequence programmed into my scan guage, and then I’ll be doing it; I seem to have a hard time getting it to set or program the right file.

 

I've never head of this. Why do it? Are there any how-to's for this?

 

I’m copying verbatim a quote from my auto tech service company from an article written by the owner of the company, plus a link to the entire article, as to why they re-torque the transmission valve body bolts, when dropping the plan and replacing the AT filter and adding Toyota AT fluid.

“While the pan is off, we tighten the bolts on the transmission valve body to the specified torque. In time the valve body gasket shrinks, from heat and the bolts loosen. A loose valve body can develop cross-leaks among the passages. This can cause transmission failure. Properly tightening these bolts can help prevent this problem.
After inspection and checking the valve body bolts, we replace the transmission filter and seal. Next we install the pan and we fill the transmission with the proper fluid. Replacing the filter is key on transmissions with replaceable filters. Restricted transmission filters lower internal pressure and can destroy a transmission very quickly.”

The 05-06 Tundra Service manual linked by weadjust in his post above provides the valve body bolt torque specification, on page AT-14 (valve body assembly) for the 19 valve body bolts (11 N-m, 8 ft-lbf) and steps are provided in the service manual.

 

I had Yodaman in Sonoma do a flush, pan drop, and re torque of the valve body. It shifted great before and still does. I trust a man that has conquered the Rubicon trail many times and kept every toyota on it running tip top.

 

Would this be Sonoma CA??

 

Uh oh. My man is planning his side trips

 

No. I just have No idea when my ATF was changed last and I don't want to get shafted by a dealer.

 

I changed the transmission on my 05 without dipstick and same as 06. I did it at 100k miles and recently at 199k miles. It's easier than you think. Drain at the bottom and fill at the side. Once the new fluid overflows at the side, then it's enough.

 

That's ok for the diffs but not the trans.

Get it up to temp and then open the fluid level check port. There's several posts about this if you check.

 

I guess somehow you have made it 100k miles with this method but fluid should be up to a specific temp when checking the fill plug. Either drain and refill the exact same as the amount drained or follow the procedure for temp rating when checking fill plug.
