To achieve the recommended torque follow these steps:
1. Lubricate the bolt threads with engine oil
2. Torque them to 30 ft-lb
3. Using a torque angle gauge - add another 90-degree to it
4. Loosen head bolts by one turn
5. Again, torque them to 30 ft-lb
6. Add another 90-degrees
7. Finally, add another 90-degrees using a torque angle gauge.
There's a module under the truck by the transfer case check all fuses what year? and what size motor? Clean and use carbon conductive grease on plugs could be from corrosion and oxidation of the contacts post back with more info and write down everything that you did and I'll get you to the problem cause I'm a taxi mechanic in NYC and I have 50 years experience in all cars and trucks remember I'm not there so your post should be well thought out with the info before sending ok thanks Stephen
Your flexplate and/or torque convertor are out of balance.
If recently replaced it should be a warranty issue.
By your testing you have determined it's transmission related.
I have seen new/rebuilt torque convertors be balanced incorrectly.
I would start by unplugging the batteries for a few minutes and letting the system reset. Plug them back in and start her up. I had a similar issue and after driving a few blocks the light went off.
There is a relay. But first check for good ground on the black wire at the compressor clutch. Wiggle while testing to make sure it's good. If so, then suspect a bad relay. Relay is controlled by the PCM
shocks will be that same bolts and rubbers as OEM equipment
they are just more robust and engineered differently internally
talk wit suspension professional shops to get the right units for your application
Without testing the electronic's , hooking up a professional type scan tool an checking for DTC'S - diagnostic trouble code's etc ... we'd only be guessing . Probably the instrument cluster,but that is just a guess . Are you aware that the instrument cluster has a microprocessor an logic . Serial data communication network the modules share info. on ? Your vehicle has 10 or more modules (computers ) . What's the voltage at the battery terminals with the vehicle running ? Viewing wiring diagrams for electrical distribution an testing with a DMM - digital multi-meter would be a next step in the diagnostic procedure ,if no code's !
Electric Testing Techniques You Need to Know
Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info. year , make , model an engine size . Under system click on body & accessories ,then under subsystem click on instrumentation . Click the search button then the blue link. Pull the instrument cluster ,with it still connected to the vehicle , check power an ground circuit's .
Try spraying some WD40 over the small switch that is half way down the front of both doors they are probably rusted up what we don't see much is what we all forget. should solve your problem. Hope this helps Best wishes, Malcolm Campbell.
