Before guessing at transmission problems, check the fluid level (car warmed up, engine running in Park on level ground) and have the PCM scanned for trouble codes FIRST.
put a line pressure gauge ($55 shipped on Ebay, or visit a local trans shop) on the pressure test port and go for a drive to verify proper line pressure. Base pressure at idle in P,N,OD should be around 70psi and around 140psi in R. Max line pressure should be at least 190psi at WOT in 1st or 2nd, 225psi is optimum. If base pressure is low, trans or pump is worn out. If max pressure is low, check EPC solenoid. If reverse is slow to engage, and line pressure does not come up to at least 130psi in reverse, replace the boost valve with a Transgo 0.490" boost valve (easy fix in pan).
Soft shifting, gradual performance degradation: Poor line pressure rise due to leaking boost valve, clogged EPC filter screen, failing EPC solenoid, or worst case: leaky seals throughout. Transgo HD2-C kit fixes first two without removing trans. Seal restorer may fix last problem, but probably R&R. Also try a transmission flush with BG brand products (Firestone stocks it).
Trans does not upshift out of first, speedometer reads zero at all times: VSS failure. Easy fix on rear of transmission, but xmember must come out to access VSS, Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.
Thank you for using fixya and good luck.

I replaced the knock sensor on my 1994 Chevrolet Silverado C3500 and my truck is still running rough and have a hard time getting above 2000 rpms. Anything above that it wants to stall out and shut off.


How are the O2 sensors? Any trouble codes stored? You can get a free code read at most auto parts stores.

O2 sensors usually don't set codes though.

94 gmc 4x4 1500 overdrive sometimes works


Check for a transmission speed sensor fault (OBDII scan). Loss of speed sensor signal will result in no torque converter lock up, and no overdrive. Also transmission filter should have been changed at 80,000 miles. Age of your vehicle(1994) warrants the filter service. Transfer case (4WD) needs to be serviced as well.

SEEMS LIKE CAR IS SLUGGISH AND LOOSING POWER WHEN TEMP IS HOT.


id maybe try going back to 87 octane gas cause 93 may make it run better but it will run hotter too and that can cause premature detonation and spark knock
