After a little searching on FB
Im thinking its the ignition switch
Aupposedly the transmission is wired through it
I had lots of transmission solenoid codes and no gear shifts, some times, like a drive home in first gear. The ignition switches are garbage 1995 and on. No codes and no shift failure after replacing the ignition switch. That was my 1995 truck, not showing below, through a fault of this site.

Your 95' will show if you click on the down arrow on the far right side of the signature. then it will expand down a bit to show

Thankyou, I just remembered that, and tried it, but it is likely that people would not know to click there, and wonder why I am commenting about a vehicle not on my list.

Thank you very much for the reply, makes me feel better, my wick has been burnt quite a while
I will be changing the ignition switch first thing in the morning
God Bless

Getting a simple fix is often clouded by complicated suggestions, I hope this works for you, the plastic on the column is a pain to remove, unlike the 1994, where the ignition barrel is accessed by removing the steering wheel and the switch that is bullet proof is under the dash.

It was a project
I already swapped the lock cylinder
And FSS
And lift pump and OPS and filters and relays and fuses and ran tons of grounds and vssb and followed all the wires, literally, and ya, I’ve put my time in.
So today is ignition switch and multi-function switch

then hopefully I can get down the highway to take my daughter hunting

No go
New ignition switch
New VSSB
New multi-function switch
New lock cylinder
New FSS
New filters
New lift pump
New batteries
New tires
New fluids
New OPS
New brake switch
New APPS
Ran a TON of new grounds
new radio
New climate switches
New fuses
New relays
Cleaned the turbo
New CDR
Solenoids test good
Vss’s test good

Absolutely no changes
Speedo is 150% faster than actual speed
No overdrive
TC is not kicking in at all

I’ve followed almost all wires

I can’t figure out how tranny gets ground

computer is not reading vssb either

computer has gotta be in default mode due to 150% speedo and the code no gear ratio selected

I’m sooooo lost

Sounds like a nightmare, info says that you don't have a vssb. I had the help of being able to swap parts from the other vehicle that was functional, to exclude the erronious codes, like vss, and tps, even swapped the ecm to exclude failure of it. I have no more ideas. It is interesting that both of my vehicles have rebuilt ECMs.

I have a vssb
I have 2 actually
A new one
And the factory one I soldered the circuits for 4.10 gears in hopes that helped the speedo
No change

The PCM in the photo in post #11 is for a 4wd.

I was seeing vssb end in 1995, but it is for gassers.

I grounded the wire which runs to the fender well on the passenger side, as well as the ground wire which runs behind the bumper and grill. I followed almost all wires necessary, except the ones which run behind the stereo.

Question, what is the cheapest way to see if the computer is sending a signal to the transmission to see if it is locking up?

The best way is use the ECM from a running vehicle to see if it cures the problem.
