sorry to revive an old thread but when you say “vibration in the motor” is it something that will break it? Or just a vibration I can learn to live with? can I just swap the torque converter from my old transmission into the new one? I have a 5.2L motor and found a cheap Trans from a 5.7L. My torque converter from my 5.2L only has 2,000 miles on it.2nd Generation Transmission
Transmission Swap (Re: 2001 318-360 compatability)
“The 46 went "RE" in 1996. Any 1996 or newer 46RE will swap.”
Note: “The number refers to the torque rating. Essentially 42,44= low, 45= medium, 46=high, 48=OMG!
The "R" stands for rear wheel drive. The "E" means electronic valve body, as opposed to the earlier 46RH which had a hydraulic valve body.”
Also… (Re: 99 318-360 compatability)
“Well Mike the trans are interchangeable . But the torque convertors are different . The one from the 5.9 is externally balanced . If you use that in the 5.2 , you will have a vibration from the motor . Yes the rear main is accessible with the trans out . I am a believer , if it's not broke don't fix it .”
