Vibration when torque converter locks up

[v8_bomberdore]

it defenetly sounds like the lock up in the converter is rooted, exchange converter is about $300

Im having this trouble too! i sent the vn to my local mechenic and he said its the center breaing its worn out. But i didnt hink the Vn had a center breaing in the tail shaft?

Used to have a VN v6, similar thing to Rob drag racer, but it was the HT leads breaking down. Once it dropped into 4th, under a slight load it felt like the rear axle was going to fall out. Very alarming!!
Manually lock it back into 3rd and it was fine.

it only seems real bad when its under load when its locked up. once it unlocks, the vibration goes away. should i check out the leads next?

 

[Greedy]

ill look into it i have only just changed the coils

 

[rob drag racer]

id check the leads like i said better to check than to do all that work and it not be the issue like red truck said its like ya diff is going to spit its self out from the vibration

ok my torque converter is stuffed i just checked their are shavings in the oil so gear box might be stuffed too. Does the torque converter from a vs fit vn? and is the v6 auto a t350 or something else?
