How to Drain/Refill Automatic Transmission

Post it here so we can all use it

 

Lol Im not sure that would be my best move

 

Used the funnel method for my D&F, worked like a champ. 1/2” hose fits in the fill hole very securely.

 

This weekend I'm doing a drain and fill on my 07 GX470 with Valvoline Maxlife ATF. I've done the change on my Taco before and it looks like the same procedures for the GX.

 

I recently had a transmission fluid leak on my '06 base, V6, 4x4 auto, which I repaired. When refilling I used the Toyota dealer recommended ATF fluid which in this case was type T-IV. Now I am concerned because it seems many others recommend using type WS for my model year. Will the type T4 be okay in my truck?

 

Your truck uses WS not T-IV. Only the 4 cyl 4 speed auto uses T-IV. I believe the viscosity is different, but I don’t know if it will cause any damage.

 

Thank you for the clarification. For those who may have the same question: I asked Gearcruncher about it and he said the same in regards to my specific transmission using WS. He also said that topping off with T4 wont ruin the transmission, but he recommended a full flush considering my mileage.

 

This is the only way for a driveway mechanic to refill an A750x transmission. Crawling around underneath with a bunch of bottles and a pump is a pain.

Gravity is a lot faster than a hand pump used in a precarious position.

 

Is the drain/refill method recommended for the 60k service OR the flush?

 

drain, change filter, fill. ran a couple miles through all gears, drain and fill again. This thread made it easy.

Old fluid looked like oil, not. probably original to my '11 tans.

 

Sub’d. Thanks OP

 

Just did this today. My fluid was very dark and thick. It wasn't til about the 3rd or 4th 2 qt. dump that it was coming out clean. I bought a 1 gallon spray pumper thing from Walmart for 7 bucks. The end fits into the return line rubber hose. Worked like a champ. Did a test drive around the block and shifting is fine. I have been having a shudder about 35-40 mph. That seems to have disappeared.

 

Looks like you just run funnel with tubing attached down through an opening in the engine bay? Is that correct? My first rodeo with this truck.

 

yes this is the easiest way to do it. some spillage removing the tube from the fill port is inevitable so be prepared for that.

 

Yes + I first attach a clean sock around the end of the hose that I feed down into the transmission fill hole. Slide the hose into the sock. Wrap a rubber band around the sock. This keeps the sock attached to the hose and keeps unwanted dirt/etc from finding it's way into the end of the hose that you feed into the transmission fill hole. Once you get the hose down below and the fill plug is off(24mm socket) - you can pull off the sock and feed it into the transmission fill hole.

 

Thanks. Did it last night. Worked like a champ. Only problem I had was somebody had over tightened the Allen bolt... almost didn’t get it out.

 

Just finished up my yearly DAF. Zero issues...as usual.

Old fluid on the left, new on the right. Old stuff still looked great.

 

I'm about due as well, need to pick up some Valvoline maxlife

 

Thanks for the brag Plain Jane, lol. I just received an alert for a new post on this thread while searching online for a trans oil cooler tube . Here is my experience, and I planned on doing a flush through the oil cooler lines.

I drained the pan and was torquing the drain plug. Before it was fully torqued, and didn't even get to the point of crushing the washer, I felt the threads pop... ugh. I was afraid some metal may have ended up in the oil pan, and wasn't sure if the threads on the pan were also damaged, so 20 bolts later, pan was off. After over an hour round trip to the dealer in Christmas shopping traffic, I had a new filter (decided to replace since I had it torn apart) a new pan gasket, and new drain plug. I was installing the pan and barely snugged the bolts. Grabbed the torque wrench and when I was on the LAST effing bolt, SNAP! Keep in mind, I'm laying under my truck in the driveway, on a seasonably warm day in NE Ohio. I grab my screw extractors and hoped I could get a grab without drilling, but no go, the bolt broke well beneath the surface, and of course, one of the least accessible bolts, on the front of the pan. So I grab my drill, and tap and die set. I was fearing the worse, as the chances of me not completely screwing up the threads on the case were slim. I started drilling (I need to buy some left handed drills) and kept trying to get an extractor to hold. The more I drilled, the more I feared how damaged the threads were getting. The Toyota Gods were shining on me apparently, as I managed to drill perfectly in the center of the bolt, and got it out with no damage! I had soaked those oil pan bolts in rust remover the night before, they were pretty ugly, but since I had my tap and die set out already, I decided to run all the bolts through a die to clean up the threads, and pulled a bolt off a 4runner I am going to part out. When I had my frame swap done, the dealer forgot to put the clamps back on the oil cooler lines up by the radiator, that was a couple years ago, glad that's not a high pressure hose! Anyway, the clamp that holds those lines firmly to the bumper was rusted out, I took that off and was going to fabricate something to hold them later, not a big deal. So I flushed about 15 gallons of fluid through the system, had everything buttoned up, put my jumper wire on to check the level, and noticed a leak up front. When I pulled that bracket off, apparently it was rusted so much that it created a pinhole in the line. I made a couple calls to my local dealership. Closest one doesn't have it, can order it for about $55, and the only other dealer open today, is about 45 minutes away, and wants $100! Guess my truck is staying put until after Christmas! I think I'm just going to order one online, I can't believe a "few hours" job turned into a few days! But so fortunate that the threads on my pan didn't get damaged, and even more fortunate that I was able to drill out that bolt with no damage. I might just save the bolt and stick it on a magnet on my tool box, lol. Merry Christmas TacomaWorld!!!

 

Like the OBD2 adapter you have....any idea where we can get one or make one?
