Vibration on slow acceleration

[ahhweewee]

I'm in the shudder club now

227k on my '05 and now it looks like I'm in the shudder club. I never had a problem until approximately 24 hours after having rear brakes serviced and Virginia State inspection. The brake mechanic lifted the rear only with a floor jack. I thought maybe he cracked a rubber boot on a mount or something. I still don't know, but after reading these posts I'm thinking it may just be a coincidence. I took it to the dealer after the brake job for the free inspection. It was ironic that the dealer recommended a trans flush and changing the fluids in the differentials. I just ignored the diffs recommendation because I had them replaced with Royal Purple two years ago, just not by the dealer. Now when I get up around 25-35 it shudders. I can feel it in the rear end and its pretty noticeable if I don't accelerate through it quickly. Now I look like I'm going for 10 seconds in the quarter mile every time I have a passenger so they don't notice the shaking.

Has anyone had any real luck shy of replacing the TC, and what did you do?

Same here!

Same thing happening here. Was there a solution?

'05 Toy 4 runner v6

I replaced my suspension (upper and lower ball joints, inner and outer tie rods, all sway bar links), bought brand new tires, all new rotors, all new pads, balanced, wheel alignment, inspected by 2 suspension specialist. They couldn't see anything physically wrong.

I do have this rumble, slight vibration about the speed of 30-40 mph. This stops when let off the gas. When I accelerate faster, I don't seem to notice it.

I wonder if this affects my suspension, the way it handles. At higher speeds, past 60 mph, sometimes feels like I have bump steer, not 100% control of handling.

If this were a motor mount or a U joint not functioning properly, it could affect both of my problems. I don't know really. It's cheap to lube my zerk fittings, I can start with that.

 

[Bamagolds]

can anyone confirm how many quarts of fluid are needed for a drain n fill?

5.7 qts

Bamagolds did lubing the zerk fittings work for you? I’m having same issues as described in this thread

I had the exact problem OP had. Not the full rumble strip of the main transmission thread. Did a full fluid swap at the dealer with WS fluid and it was back in 10k miles. Did a single drain n fill with Maxlife and 5oz Lubeguard Red and it’s gone. Gonna let the Lubeguard and Maxlife clean up the crusties in the transmission for about 15k, then when it’s at 200k do a full swap again with Lubeguard Red and Maxlife.

I am having this same issue with my 09 sport.Only during a slow a celeration between 20-30 mph the whole vehicle stutters -feels just like washboard - and the stutter is especially pronounced when I drive uphill.

Problem does not occure in rapid acceleration or other speeds.

I too am now having similar symptoms... It only happens while accelerating, most often between 25-30mph. It seems to be coming from the passenger front. The only difference in mine is that I can't feel it so much through the steering wheel, mostly the whole front end. I had not noticed this at all until the day after a big rain and we were driving through a bunch of deep water, (sometimes at speed :surfer At no time during the drive did I feel / hear anything terrible happen, but starting the day after, this vibration is now a daily occurrence.

The vibration only lasts a few seconds and then stops. I will be trying to use my GoPro to film the suspension / engine bay components to see if i can determine what might be causing the problem.

Anyone else have any ideas?

What you describe sounds exactly like torque converter shudder and is usually solved by doing a complete transmission fluid flush and most also add the additive Instant Shudder Fixx which can be found at most auto part stores.

Do a separate 4th Gens forum search for all of these phrases/words...Shudder....rumble strip....transmission fluid flush....Shudder Fixx... for more details.

Did you ever get this problem resolved? I’m having the same issue in 2008 sport edition. Started happening after the 4wd binded up.

Same problem, happened last sat after 5100+ome+1.5 rear spacers install.
Will grease up zerc fittings and report back.

greased zerc fittings and replaced l/s wheel bearing, alignment next week. feels much better already.

I have this same problem. Shakes/shudder when I hit about 1900 rpm going around 30 mph. Does it more if I'm on an incline. Does not do it if I step into the throttle a bit more or accelerate quickly. I've searched this forum, others, youtube, etc. I've concluded that it's a common problem with the torque converter and not much you can do other than replacing torque converter. Many have suggested using shudder fix. General thoughts seem to be that it's annoying but not detrimental and no need to spend the money.

Mine didn't go away entirely. I can still fill it a little bit. Not sure which solution made the difference. I still have anti shudder additive in my toolbox, never used it.
