The Warden]However, at low engine speeds, you'll get a noise (commonly known as gear rollover) from the tranny with an SMFW that is generally not present on a DMFW.
With my SMF what I've found is I get the "roll over" sound in low rpm up to about 1100 taking off....in whatever gear I take off in, 1st or 2nd. Under a load it tends to give more shudder till clutch can get fully engaged.
Reverse is worse yet, especially up hill, or loaded, or more worstest of all, loaded & uphill. I still think Ford in their wisdom geared reverse about 2-3-4 times too hi....just my opinion. But I've never seen anywhere yet I had to get to very fast in reverse!!!
I had some of all these same problems with my original DMF, but more with the SMF I installed.
However, I must say, my SMF been in there round a year & it seems to be getting somewhat better about all shuddering etc...explain that????
Another thing, I was already running a heavier oil in my hi miler ZF, but I went to some really heavy oil plus over filled it....over 2 gal.
Have to shift slower in cold weather till it's warmed up.
