My truck is a 96 r1500 that had a 5.9l and last summer i installed a 95 5.2 both were auto's but did they both have the same torque coverter which is weighted for balance or are they different ? The flex plates looked the same when i did the swap !

 

Is your truck vibrating?

 

^^^ No the flex plates are different from 5.2 to 5.9 one is weighted and the other is not, if you searched this forum or the web you would see that.

Edit: @ aofarrell2 Why did you edit your post? I don't edit my posts if I am wrong leave it there so people can see what's right and wrong.

 

I thought they only started putting the weights on the flex plate starting on or after 96. Before they were on the torque converter. So your 96 5.9 probably had weights on TC, and the 95 5.2 wouldn't have had any weights, TC or flex plate on the truck it came out of.

So if your flex plates were indeed the same, that means the 5.9 had weights on the TC, because it had to have them somewhere. If you reused the torque converter, then they should still be on there. I had the 5.9 in my durango replaced by the 5.2, and finally traced a vibration back to this issue. Dropped the tranny, removed the weights, and the problem went away. The vibration was not highly noticeable, some might confuse it for something like a rough patch in the road, and it was only above about 2700 rpm. Below that, it still ran super smooth.

 

Are the weights on the flexplate side ?

 

Yea i wasn't gonna use the converter that came with the motor because i didn't know about it and my trans and conv only have about 10k on it since rebuild !

 

Any info guys ?

 

Yes weights are on the flex plate. 318's are internally balanced motors, while 360's are externally, so you need to install the correct flex plate. 360's have weights on them, 318's do not.

 

The flex plates were exactly the same when i had them out ! Somebody said the weights are on the converter ?

 

No theyre not. They are weights on the 360 flex plate. You dont have a 360 plate if neither had weights, the 318 plate should look a little thinner.
