Silverado 2500HD SHIFT INHIBITED, LIMP MODE, NEUTRAL SAFETY, FIXED

[@brians.1247]

I'm not sure when you made this video, but just cleaning out the plug and using dielectric grease is only a temporary fix because the source of the transmission leak is behind the plug and would need to be replaced and they would sell that trans Connector harness that goes in the transmission to fix the problem.. I just did the job myself for my 2001 chevrolet silverado 2500hd

[@affinityfunable]

Yes your right. I've had to do the harness replacement on my current Duramax. Don't buy the cheap ones on scamazon either. Get a quality one.

[@chuckheinch]

I had issues also. Finally had the service done. The internal filter malfunctioned and blew out the side. It would go into limp mode every once in awhile. Once I replace the filter I never had any issues.

chuckheinch wow, you just made my night sir. I’ve spent all day today stuck in a parking garage staring at a SnapOn scanner going through tests & looking at data etc. It’s done it a few times in the past 10 months if I accelerated hard in first in tune 3 or above. Tomorrow I will definitely be dropping the pan & replacing that filter! You just saved me a lot of time. Thank you!!!

This got my 01 lb7 back on the road. Thanks a million.

[@Calhoun1186]

Replaced my switch after new torque converter was installed.. same thing. Was wiggling around and when I checked that bundle I stoped throwing codes. Thanks for video!!!

[@affinityfunable]

This fixed my issue for several months.

[@affinityfunable]

That fixed the problem.

[@affinityfunable]

Yes for a few months. The permanent fix is to replace the wire harness connecting to the solenoids.

[@greglay7425]

Did that fix it?

[@affinityfunable]

That's why I posted it. This was the fix. I sold the truck shortly after that for an LBZ Duramax which also had the same leak thru the plug. The permanent fix is to replace the internal wire harness. It is acceptable when the pan is dropped. It can be serviced without removing the transmission. Make sure and buy a replacement from a reputable shop though. The cheap harnesses leak again in a matter of weeks.

This video was like being at a party and telling a joke to a crowd with no punch line.

[@cholochedd6752]

You said with the Duramax transmission ?

[@affinityfunable]

Yes. This is an Alluson Transmission.

[@user-wj9wq7mk4h]

Does my 8.1 gas engine have the duramax transmission?

[@mrdanger4004]

How did you get that wiring harness off?

[@affinityfunable]

They are assembled with a waterproof type grease I believe. My favorite way is to spray them with a penetrating oil then slowly rock them back and forth as you release the plastic pin. Reassemble with dielectric grease.

[@scottdarby7120]

@@affinityfunable "The plastic pin?" how do you release the pin? pinch? pry? press? where is this pin?

[@jarednoland274]

@@scottdarby7120 cleaning the connector is important. Clean it and release the connector with your finger or a pick or screw driver

[@robertsalas3984]

And did it fix it

[@affinityfunable]

Robert Salas yes it did.

[@tannerroberson7309]

[@affinityfunable]

Tanner Roberson Tanner did you check this connecter on the passenger side of the truck?

[@evanliska7384]

Did it throw a code

[@affinityfunable]

Yes. Shift inhibited came on the information window. It just stopped shifting also.

[@NomadXplorer]

......but did it fix it? Thanks for a goose chase? Wow.

[@jarednoland274]

Yes that fixed the shifting start problems all together
