6L80E out of a 2010 GMC Yukon XL Denali with a L94 6.2L with 119,xxx miles........And of coarse the Torque Converter failed & filled the unit with Aluminum & Steel debris from the TCC clutch wearing out allowing the Clutch Piston made from Aluminum to grind into the Steel Converter Cover.
The good.....
*The filter did it's job & kept the grindings out of the Geartrain, Valve Body, & TEHCM.
The bad.....
*The Pump Body which is integral to the Bellhousing is trashed along with the Pump Cover/Stator.
*As this happened while the owner was on his way back from a Casino in Oklahoma & he decided to keep pushing it......The 4-5-6 Clutch got burnt down from lack of Line Pressure. All the other Frictions just have normal wear for 120,000 miles
By the time it got towed to my shop.....The vehicle would move under it's own power for about 15-20 seconds then fall out of gear......Let it sit for 10 minutes, Then it would move again for 15-20 seconds. The reason for this is, The filter would get loaded up & starve the Pump....Letting it sit would allow just enough debris to fall out on the filter to get some line pressure back.
I could also hear when the Pump got starved.
The owner thought a Transmission Service might fix it......Yes Sir......It needs a $4,500 Transmission Service!
What will be performed & parts used.....
*OE Pump Body/Bellhousing
*OE Pump Cover
*OE Pump Kit (Rotor, Slide, Vanes, Rings)
*OE Filter
*OE 4-5-6 Steels
*Sonnax Line Booster Kit (Boost Valve & PR Spring)
*Sonnax Pump Primer Spring.
*All Bushings (Durabond)
*All Bearings (KOYO)
*Borg Warner OE style Frictions
*All new Seals & Gaskets
*Seal Aftermarket High Performance "Blue" Clutch Pistons
*Sonnax Billet Converter Cover & Multi Disc Converter Clutch using a stock JMBX Stator & Turbine (Stock Stall)
*New Radiator (Trans Cooler)
*New Auxiliary Trans Cooler
*Tuning via HP-Tuners to turn off the AFM & eliminate the TCC PWM apply.
*Valvoline Maxlife Synthetic LV ATF
If you own a vehicle with this unit......DO NOT ignore the SES light & TCC Slip DTC's! Or any strange trans behavior for that matter! $2,000 of this Invoice could have been avoided. But it's not in peoples nature to be Proactive about Transmissions.....Only Reactive.
