    I just replaced the transmission in my Proline with a new 4 spd from J-Thomas, and it is moving a noticable bit slower than the old 4 spd. It is the same exact type of peerless transmission. Willl it wear in and speed up, or is there some sort of adjustment. Any help is appreciated.

    There is no adjustment on these transmissions, The only thing I can figure is the old one was wore out and had wider tolerances (less drag) than the new one set at factory specs., When it starts to wear it may get a little faster but not like the old one.

    With the different model #'s on the Peerless trannies, the gear ratios are different, thus a difference in speed in a set gear. You will have to shift-up a gear to make the speed difference. Get a Peerless Manual, and it will show you the gear ratios and their respective speeds. Someone along the line made a change. Either the model numbers are different, or someone changed gear ratios on you. It happened to me once. I just shifted up a gear and went on for a few more years.

    thanks for the replies. Is there any way to change the pulley beneath the transmission to gain more speed. If not I guess I'll just have to deal with it.

    Sure you can change the pulley but you have to find one with the same off-set as yours and sometimes that can be fun.

    Will a larger or smaller pully increase the speed. Thanks

    I was wondering if anyone was going to ask that question.

    The transmission pulley needs to be smaller to make the machine move faster.
