Vibration at low speed

[Mattbchillin]

I have this same issue in my 2008 with 145K on the clock. After I pull out of my driveway I have a slight hill that I have to go up and since I drive for gas mileage (hahah I know) I tend to accelerate at a slower speed then everyone else. I just assumed it was because it was cold and not warmed up properly or ruff roads. I will have to see how it does turning and accelerating at slow speeds. I recently had the rear diff completely re-built so I hope vibration has nothing to do with that.

How did you make the video because I recently got a gopro and was tempted to video the engine because of this post.

Mobil 3309 and Toyota T-IV are the most commonly used replacement fluids for the AW5x and TF-80SC transmissions as far as I have ever used or seen. Other fluids are JWS 3309 compatible but these two fluids have been used consistently over time with good result. I have used the Mobil 3309 product for 10 years and have done 4 fluid replacements on my cars. Both shift great, no reported issues over time. Used to be tough to find a case locally, had to get it from a wholesale distributor drop shipped to a local oil change place back in the day.

Somewhere in 2010 or later (after chassis 568001) https://forums.swedespeed.com/showthrea ... (JWS-3324), the JWS3309 TF-80SC fluid gets changed to a JWS3324 (AW-1) fluid, although it appears the V8 is excluded from the change. Someone brought up improved fuel efficiency with a slightly thinner AW-1 fluid but this was never proven. The "why" remains somewhat of a mystery.

Summit Racing, that's where I purchased it; good price $26.99 for 6qts.

And for amsoil, this is their compatibility specs for one of their trans fluids:

I changed the fluid with Mobil 3309 a few weeks ago, but I haven't had much time to drive it because I was out of town. However, I did notice less shift flare, and less shutter. Give me about a month to get a better feedback on the fluid change.

For the video recording, I used a Nikon coolpix with a large diameter washer screwed camera mount. I attached the camera to the lower control arm with a strong magnet. The torque converter shutter was evident when I was recording the driver side CV axle going into the transmission. With that view I could see the transmission bounce back and forth. Here is some video:






The next thing is looking into a diagnostic tool. Any suggestions?

I decided to change the fluid in late October 2018, using Mobile 3309. Its December 06, 2018, and here is my feedback. The shifting seems to be a lot more smoother and I hardly notice any shift flares from 2dnd to 3rd. The shutter seems to have minimized by at least 75%. I still have shutter, but you really need to control your acceleration to make it happen. I will give another post as time goes on. So in my opinion for those who want to change your trans fluid for this type of transmission, use Mobile 3309, and DO NOT USE AMSOIL. Amsoil may have some good products, but their signature series trans fluid seems to contain something that caused too much slippage. I had the same outcome on my Harley when using Amsoil primary fluid. It caused clutch slippage which was confirmed by two different independent dyno testings. When I called Amsoil about the issue, they asked if the engine had any upgrades, to which it did. The associate related their primary fluid is only for vehicles with no engine upgrades. What a crock of BS. Have a good holiday dudes.

It's March 20, 2019, and there is no longer have any shutter, or even shift flare for the past two months. The transmission operates great. So in my opinion, stay away from Amsoil and use Mobile 3309.
