915 Transmission shift 3-4-5 problem
The shifter in my 1978 Porsche 911 has no resistance going to 3-4 -5th gear.
1-2 gear is spring loaded to the left, but when I go for 3rd gear I easily end up in 5th gear with zero spring load. Is the problem the shifter or the transmission ?? I bought the car that way. Thanks, and greetings, Harold

A stock shift lever is not spring loaded to the left. Only 5th and reverse are spring loaded.
You may have an aftermarket set up. Take a picture of it.

Could be shifter bushings, shift rod coupler, or the guide fork in the transmission came loose.
Pull up the shift boot and take a picture so we know what shifter you have.

I’ll put the money on the guide fork on the inspection plate
If that’s the fault replace the whole plate and fork, don’t try to fix it Bruce |

more shifter woes
Turning part 3 around would also not work.
The shift fork is for a standard shifter while all other parts are from a short shift kit. So need a short shifter shift fork. WOW

An early SC 915 shift housing illustration follows:  Not sure why your factory stock 915 shift lever has spring tension on the 1/2 side. Typically, only on 5th/Rev. AFAIK, a 930 4-speed turbo shifter doesn't have any springs The issue may be due to a worn front shift shaft bushing (item 22 above). Excess play here prevents the lever from selecting the proper gears.  Sherwood |
