smr transmissions did a comparison on a small block dodge dakota between a 727 and a 518. Lost a full second e.t. with the 518. Same truck, engine, rear and track.




I'm sure a company that specializes in 727 and 904 AND sells the gear vendors units is absolutely unbiased.

Where's the data? Specs on the transmission builds? Was this a bone stock w/ stock converter 518 left in drive versus a 727, converted to roller internals with an aftermarket converter, valve body and shifted manually?

Take a stock unrebuilt 727, stock unrebuilt non-lockup 518(so you can put the same converter on both) and actually rebuild both transmissions COMPARABLY. Then run then down the track 10 times each and get back to me. Until someone does that, everything is heresay and myth.
