You get a shaking that feels kinda like an out of balance drive shaft or tire(s). It starts above around 35-40 mph if I remember correctly and only goes away(temporarily) if you let off the gas, stomp on the gas or tap the brake pedal.

hey hey thanks for the quick responces!! You guys kick ass! This is re insurance I heard it was either the rear u-joints or T.Q.!!!!! I just did complete rebuilt on my rear drive shaft! So now its gota new rear end + t-case. That was before my time with it.

also can a bad t.q. mess up the shift patterns. Like for a while it wouldn't shift into 3/4 gear. I did a tranny flush and it drove fine after that. So maybe that was the start. Ever since I bought the Bronco is had the Bucking feeling. So I saw this website and added that as my screename! Tires are balanced good! Rear is good, drive shaft is great!! t-case was new about 50,xxx miles ago. So other then the bucking part is runs great! when it bucks I get off the gas then keep driving.

what would a shop charge to install a new T.Q.? An arm and a leg? I know its cheaper to do myself. but it looks to be a pain. But willing get r done myself. :)

yeah that was my next question was how much they usually go for? $150 not bad. If I did it myself do I just take the t-case out, and unbolt the the t.q. from flywheel, then unbold the tranny from the engine, tranny mount then slide it back, slap in the t.q. then bolt everything back up. Do I add t-fluid to the t.q. before installation? then finish filling up the t-fluid after everything is intact?

Whats a decent one to get. Would if be ok to get a stall converter on a Bronco? I know many mustang boys with thier automatics get them. So I had to ask.

thanks again man. :)

it would be easier to just unbolt your rear driveshaft and then drop the tranny. make sure you torque them down to specs.

Also a semi-related question. How do you know if a torque converter is good or bad, if it's off the truck? Is there an inspection?

what size is it? Will a t.q. from a AOD tranny fit too? doubt it but had to ask. Summitcracing doesn't carry sh*t :(

Might want to give a description of your problem before jumping to just a tq converter problem.

Reason I asked if it could be tested off truck, is I am getting a C-6 with T.C. from another FSB member and he said I should check out the T.C. first. It would be a real bummer to install the trans and have a bad converter and have to take it all back out. Probably best to just replace it....

EDIT: Sorry for the partial hijack !

Take it to a trans shop and have them check it out for you.

read it.

Everyday that I drive it ever since I've owned it, allmost a year now. Its done that vibrationg after 35 mph. on the freeway its worse! The whole truck shakes, similler to a u-joint going bad but the vibration is twice as bad.
35, 45, 55, 65 mph it vibrates. I've never drove it over 70mph for fear that truck may fall aparts.

last summer, the tranny wouldn't shift into the 3-4 gear. took it to the tranny shop, they said the fluid was a quart low, and then hooked it up to thier Snap On scanner. It said the T.Q. was slipping.

So by having this wicked vibration I was told it could be 1 of 2 things. 1 is u-joints very common on going bad in Bronocos. 2 being the T.Q. Afraid of that I decided to replace all three u-joints on my rear driveshaft. greased them and everything. Test drove it and samn it still vibrates the same! So now im willing to try replacing the T.Q. If that doesn't do then I dunno what it is.
Oh yeah called every parts store around here, and all have to order them and will take a week to get here.

To find out for sure if it's the TC go for a drive and get on a straight away where you can maintain a constant speed for a little bit. Get up to around 45 mph or so where it's doing it's vibrating thing and maintain that speed(foot still on the gas, not cruise). Without moving your skinny pedal foot, tap the brake pedal with your left foot. If the vibrating stops immediately then starts back up in 2-3 seconds then it's definitely the TC.

Yep,
drove the Bronco today on the freeway, and got up to 50mph then it did the vibration thing. so i then left my foot still on the gas at the dead speed of 55 mpg I then quickly lightly tapped the brake while still on the gas and then the vibration stopped right away!!!! Then is came right back, so I then did it at 55mph same thing tapped the brake then it stopped, then came right back. did it at 65 mph again. so looks its the t.q. yhen :rofl:

I know, I've been looking and callin part stores. None have then in stock, all said they'd have to order it and can be here in a week. I've even called a few junk yards too. Ohwell I'll keep on searching. All were priced around $200 and had a $75-90 core charge.
