Tech Question - PRND2 light goes out- Tahoe runs rough- If light stays on, tahoe runs

[meduso99]

95 Tahoe. When the PRND2 light is on, the tahoe runs great. When the light doesn't come on, it runs sluggish and barely moves. Replaced VSS -speed sensor on rear of transmission but to no avail. Took Cluster out to make sure connections were intact. No luck, but when I put the cluster back in, light came on to prnd2 and I drove it, but when I returned, and shut it off, and retried, the light didn't come on, and tahoe ran rough..
I thought maybe it could be the neutral switch or ignition? Also thought it could be a bad break in the solder on cluster or even wiring ???
I did check all the fuses, but all show fine..

any help ?? [email protected] Kenneth

"trans"fuse circuit feeds all that plus speed and tach power as well. if those two are fine there is something wrong with the wire splice after fuse output. pink colored iirc.
