The saga rolls on and now have plenty of experience on whats not wrong with the beast. Back to square 1 with the fuel tank. The vans not shifting and anti lock brakes not working due to a bad connection within the tank that was over looked when pump was replaced. Went through every friggin wire back...

Well since raising everyone's eyebrows I may as well let you know that this missing relay is a "Brake/Shift Interlock Relay". Replaced this bugger with one from Wrecker and the Van is running with Speedometer, Anti-lock Brakes, Transmission (kinda) shifting , and Instrument Cluster lights ...

Thanks for the feedback Crash. From what i read you pretty much figured it out with a similar amount of energy, patience and stubbornness. Yes it could have been helpful back in JUly during my most troubling times. LOL!

Well after a few breaks from this gem I have narrowed down to a code24 - VSS circuit low(transmission output signal). This being said traced and checked wire harness from VSS sensor all the way to under the dash VSS buffer, aka DRAC on this model. Checked for power and continuity from buffer to spee...

You sure it is 1st and reverse and not 2nd and reverse? When something is wrong with the electronics in a 4L60E it goes into "limp" mode. Limp mode is 2nd and reverse. n It very well could be Second and Reverse, no tach, no tell RPM's. Will check connection at trans and change out if need...

Okay now that we all got it figured out as explained by locdoc. Did a code check and have code 24 VSS coming up on the 95 Stro. I'm suspect that this may be culprit for 1st and Reverse only. Very little knowledge on my part and cannot find resources for test procedure on this sensor. The Haynes manu...

Your 90 does NOT have a 4L60E. It has a 700R4. Also known as a 4L60. The 95 is electronic. The 90 is not. So the answer is no. The only interchangeable transmission for a 95 is................you guessed it. A 95! LOL, thanks locdoc for getting me politically corrected on my misunderstanding aka 4L...

I'm having problems with my transmission in recently "brought back from the dead" 95 Astro AWD and wondering if my 1990 Safari AWD 4L60E will swap into the 95 Stro. One would believe it should, but being that the 95 is some kinda hermaphrodite model with mostly nothing else interchangeable...

Congrats on finding the main problem! There are no vacuum lines to the transmission. Unfortunately I can not remember off the top of my head what vacuum lines are where you indicated on a W engine. If it is a long hose chances are it goes from a tee in the manifold to a "bubble" under the...

Thanks v8famvan, surely is a great feeling since being defeated by this problem many times. Feels real good realizing that others with far more superior knowledge were defeated with far more hours lost. Small price to pay to recognize who can troubleshoot till near death at times. LOL! So the van is...

Is the ECM getting power? If the bulb is good, and it doesnt light up I'd check that or the bulb and power wiring. Scott After taking a break from this nightmare I went at it once again earlier today. Was still stumped on why only power to one side of SES bulb, nothing coming back from PCM/ECM. Che...

No ground wire on the PCM body. All grounds are through the wring harness itself for the ECM. And yes, all direct grounds are either solid black or black with a white stripe. There are other indirect grounds that are other colors but they all eventually splice into the black ones. Like the tan wire...

Ground (earth) is GREEN, not black. Black is usually a hot return. Well maybe the (earth) is green in some places dude but what I'm looking at in a PCM diagram is a black/white as system ground(2), perhaps tan off O2 sensor too. "Black Hot return", Hmmm are we confused with house wiring. ...

Is the ECM getting power? If the bulb is good, and it doesnt light up I'd check that or the bulb and power wiring. Scott Thanks Scott, been waiting for some extra time to check on things again. Bulb is newly replaced, power at wiring, just need to figure out how to test ECM for power. What actually...

Well this the saga just deepened with more electrical issues or misunderstandings. Have 12volts from pump to fuel relay. Continuity from all wire within tank to relay. Checked relay a second time by removing entirely from socket this time not referring to Haynes ridiculous explanation. Relay was NFG...
