    Engine Power Is Reduced - Ongoing Issue, Updates throughout thread.

    I was able to get the following data from my scan tool, I didn't think to look at the live data. 2wd: (Automatic Transfer Case) ATC Range Switch: 1.97v ATC Range Select Switch Reference: 5.00v Range Actuator Position Sensor Voltage: 7.60v Range Actuator Direction Signal: 4.15v Range Actuator...

    Engine Power Is Reduced - Ongoing Issue, Updates throughout thread.

    I checked every connector, every ground that I could possibly find..and cleaned them well. Same codes are being stored in the TCCM. I also attempted to connect the ground under the driver side door directly to the battery and I'm still getting the same codes. Also cleaned all the...

    Engine Power Is Reduced - Ongoing Issue, Updates throughout thread.

    When I replaced the fuel pump module assembly, there were very fine metal flakes clogging the sock and all around the bottom of the white module cup that contains the pump. The dealer advised today that most likely the pump motor was the culprit. As a result the pu p probably pulled too many...

    Engine Power Is Reduced - Ongoing Issue, Updates throughout thread.

    Oh. Battery is a year old. I have the hall monitor unplugged and has been for several years now. That stopped my annual battery replacement issue. Cables are clean and tight. Stored in the garage, no critters or bugs.

    Engine Power Is Reduced - Ongoing Issue, Updates throughout thread.

    So I got the fuel pump control module replaced and programmed today, those codes are now clear. Verified that the 4wd system works. No CEL/service 4wd light illuminated; for $15, I swapped the selector switch and also did a relearn on the encoder motor. All bi-directional tests operate as...

    Engine Power Is Reduced - Ongoing Issue, Updates throughout thread.

    Vehicle is a 2013 Tahoe LT Z71 with 90k. Max towing pkg, two speed transfer case (2hi, 4hi, 4low & auto 4wd). Fuel pump failed and also the fuel pump control module. I swapped the fuel pump today and I’m waiting on the FPCM to arrive at the local dealer. I checked the modules and noticed there...

    Used prices and "the recall"

    Used prices and "the recall"

    agreed. I had a 2008 Tahoe Z71. Total POS. Buyback 2010 Tahoe Z71. Total POS. Buyback 2011 Tahoe Z71. Not as bad. Leaked oil from ever single seal and gasket. Buyback 2013 Tahoe Z71. Special ordered. Perfect. The 2019 RST we also have has been great.

    Charging system upgrade

    I do have a DR-44, actually just replaced it. I may get one of these as when the cooling fans come on, there's a significant momentary voltage drop until the system can catch up.

    Thoughts on extended warranties

    5 transmissions and was ready for a 6th when we traded it in. We bought the vehicle from my wife's parents with 69k and traded at 130k. Older folks who babied the vehicle so it certainly wasn't abused. The first transmission the warranty company paid for was a reman, I paid the difference...

    Charging system upgrade

    I stand firmly corrected! Thank you for taking the time to lookup the information. I'm pretty sure it's had all the updates, cable changes, etc. Oddly enough, once I disconnected the RVC, I have had zero battery issues. The batteries stay charged and are no longer plagued by bad cells...

    Charging system upgrade

    My 13 tahoe has gone through countless batteries. All brands. The last three that I have warrantied out have been Optima Yellow Top's -- three D34 and so far two H6. I disconnected the hall sensor on the negative cable and guess what -- no more battery issues. I was lucky to get 6-12...

    Thoughts on extended warranties

    Thoughts on extended warranties

    I have ALWAYS come out wayyyyy ahead on extended warranties, with the exception of my 13 Tahoe. I broke even on the Tahoe warranty. I paid $1835 for a 60/75 through GMEPP purchased at James Black Cadillac. Purchased at 2yrs @ 21k before the next pricing bracket at 24k. My time ran out...

    When to trade in?

    So I have a 13 Tahoe Z71 4wd with all the options and sitting at 83k; purchased when it had 3 miles. I am really itchy to get a Yukon AT4 or a Sierra AT4, although not needed. Apparently the used car market is NUTS and I can easily get 20-23k as the vehicle is absolute mint. 20k is a nice...

    Rough Country forged upper control arms?

    I have them. They are quality but with factory wheels and 285's, you'll need wheel spacers.

    Can I use my stock UCA’s for a 3” lift?

    at 3", your ride is going to be terrible and *really* stressing the upper balljoint. RIP to your balljoints.

    Upper control arm rubbing BAD w/ RC & CCM

    I'm pretty pleased with it so far. I only did the front 2.5 -- the front sits about 1/2-1" higher than the rear and does not have the fag sag. No issues towing moderate loads. I'm iffy on the control arms. It most certainly improved the ride quality, however the tires rubbed super bad at...

    Has anyone modified or moved the windshield washer fluid reservoir for more wheel well clearance?

    I’m having the same problem with factory wheels and 2 inch wide spacers on 285s. I don’t see why you can’t use a heat gun to heat up the plastic tank and slightly remodeled it. That’s what I did with the wheel liner

    Wheel Spacer sizing

    Here was my situation: I have a CCM 2.5 up front with Rough country UCA's. Stock wheels and 285-65-18 duratrac; the tires rubbed the UCA like hell. The rear fenderliner rubbed on the tires due to the wider sidewalls over the BFG all terrains of the same size. Installed 2" bora spacers...
