Thread: Flexplate Dustcover

Tweet

How necessary is the flexplate dustcover on a 350 w/700R4 tranny? It's a new crate I've had for 2 yrs while I have been building my truck (51 chevy) won't be too much longer and I'll fire it up. The only place I've found them is at the local chevy dealer parts dept. They aren't cheap and if I don't need it...

I've run motors for years without one. Dust, oil and grease collect evenly on the converter and keeps the motor in balance.

we trimed the tips of the ears off of them. to get the trans in and out with out pulling off the headers so that wee bit was were to bolt hole was for the dust tin so they never went back on they just get in the way from checking the stall bolts .i like to check them every now and then anyways if you loose one at 6500 sounds like someone is shooting at you

THEY used to say that without the dust cover( on any engine/trans) that the airflow across the area would pull oil thru the rear seal
