Trouble shooting trying to shift B&M ratchet

I've got a chevy 350 turbo trans with a B&M ratchet shifter on it. It will shift fine in drive and if i ratchet it from first. The problem tho is that it is very difficult to shift. From park you have to pull back really hard and it feels like it gives at a point then goes back quickly through a couple gears. trying to get it to shift 1 gear or slot is hard without it going up or down too far after strong arming it to get it to move. What can i do??

Can't say if there's a problem or not the B&M Ratchet shifter is always a real strength tester especially coming out of Park.

You can try adding some lube to the mechanism and check the shifter cable when worn or if the cable is the short version it can get kinked, these things add to the misery of using this shifter. The other suggestion is driving habits, be sure to be fully stopped with the parking brake well applied before shifting to Park so as to prevent the parking pawl from becoming wedged.

shifter

I have the b&m hammer that is a ratchet shifter as well and had the same issue... what I did to fix it was to grease the crap out of it for one... then the shifter has a pring that goes into the notches for each gear.. the trans has the same inside.... So i took some of the bend out of the one on the shifter end and it seamed to help. I am no longer shifting all the way to drive from park... Now I can get right into reverse from park... I hope this helps...

I had the B&M 'Z' gate in a T-bucket years ago (the innards on all of them look the same, cheap to expensive versions). Unless I greased it pretty regularly, a real bear to shift, including NOT shifting out of park occasionally if I forgot

You didn't mention which B&M ratchet you have. I'm running a B&M Quicksilver and am very happy with it - very smooth and the detents are right on. These shifters can accomodate both 3-speed and 4-speed automatics - the installation of the B&M cable to the trans is different depending on how many speeds your trans can shift through - you would want to be sure yours is installed for a 3-speed. Also on mine you lift the shifter handle slightly to take it out of park or it's a bear otherwise.

Ive always had this problem with the b&m shifters, I've tested the cables, shifter and linkage on the tranny to no avail, when the shifter is dissconected it seems alot better but when its hooked up, not so much, also have a problem with the shift indicator cables wearing out quickly, must be some kind of engineering flaw to do with the leverege of the shifter verses the linkage, the guy who designed the thing must have been a bodybuilder, lol

This is what I would do.
Hook every thing up as used. Shift hard? Shifter/ Cable/ Trans
Disconnect at trans and try it. Shift hard? Shifter/ Cable
Disconnect cable at shifter. Shift hard? Grease shifter

I disagree B&M makes the best auto trans shifter out there. I have 3 of them in my cars and never had the first bit of problem. Sounds like an install or user problem. They sure as heck beat the Hurst and Lokar models, for reliability, ease of use and built stout they have the history on that in their favor.
