You may be able to adjust the spring in the handle or find some other way to make it a positive stop, but mine's an air shifter so I never really cared.

I found that if you just hit the lever with your palm or finger--like a slap stick shifter--it'll go right into 2nd gear and not skip to 3rd.

thats exactly it . Thanks !

What is the proper method for accurate adjustment?
The primary check is for full travel from park to the opposite end of the shift pattern. Then verifying that all forward gear positions are in a relaxed condition is recommended.

Had this exact problem with one I worked on. PPP showed less than z-e-r-o interest...never returned multiple calls, emails, etc. Tossed the junk original spring and sourced some spring stock from McMaster Carr. After a bit of tinkering with spring length and preload...problem solved. -Al

heard the same from many that had issues over the years and this is why I never considered this shifter when I decided to swap out my Turbo Action Cheetah shifter 4 months ago.

I also considered the M&M and Motion Raceworks shifters which are available for both 2 and 3 speed trans, both very nice and made in the USA.

The side plates on your PPP shifter are worn out. Replace the side plates and it will work as advertised. I know because that happened to my shifter.

I'm fighting a similar issue with the shifter hitting 3rd but the trans is not fully engaged. PPP solution was to lube the cable(which I did) or get a longer cable. The PPP seems to be sensitive to the bends in the cable.
