4.11 swap - aftermath
Well, my mechanic buttoned up the car yesterday and I took her out driving. Everything seems fine, no binding around corners, FIRM shifts compared to my slipping stockbox, and ACCELERATION
![]() (your money order is on its way Tom) Seems I'm having one issue: when letting hammering the gas or letting off the gas at highway speeds, there is a loud rattle coming from the center of the car. Im HOPING its just loose exhaust shields... thoughts?

Its a REALLY noticeable scraping/grinding rattle, if it helps, it also does it as soon as I turn the key to start her up

If not the heat shields it COULD be the Torque Converter bolts being loose. They make ugly noises. They're also not a huge deal to check.

how should i got about checking them? pictures or diagrams would help.
my mechanic reused the torque convertor from the 4.11 trans... is that going to be a problem down the road? or will it be fine if I don't romp the car

my guess is that your flexplate actually came loose from the TC
![]() ![]() -Bill p.s. you can see the flexplate bolts through the access hole at the top of the passenger's side of the engine -- there may or may not be a rubber stopper in the hole.

would it be normal for some trans fluid to leak during this process?

Another possibility is that a cracked flexplate completely separated...
Where there any harsh noises when you lost power? How much fluid are you talking about????

no horrible noises, i shifted down to 2 and it 'caught' for a few seconds and held power but then revved freely again. Not much fluid, probably half a quart at most

take a look through the access hole and see if you can see the flexplate

![]() You should ONLY use SVX torque converters, or 4,44 torque converters, and THOSE only with 4.44 transmissions.
