Not too long ago, I swapped a LQ4 6.0L into a 2003 Chevy Tahoe for a customer to replace the leaky/noisy LM7 5.3L, I advised him that the stock 4L60E will last however long it lasts. He called me yesterday & said it was slipping at full throttle. He brought it in & I confirmed it was in fact flaring during the 2-3 shift under full throttle.
Advised him to take it easy 'till we can get a 4L65E built for it as he didn't want to do without his truck for a unknown length of time for me to build his original unit to 4L65E specs along with my upgrades as parts can be severely back ordered right now. I'd rather put used OE 4-Pinion Carriers in than new Chinese 5-Pinion Carriers! Pure Garbage. It's not me pushing 5-Pinion Carriers either because 4-Pinion Carriers would hold-up just fine in this application.
He frequents internet forums & is convinced he needs them, Who am I to argue against ME making more money?
I did him one better......I found a Real 4L65E out of a 2004 AWD LQ9 6.0L Escalade at a local yard that I deal with often. They wanted $850 with a 90 day warranty.....Got it for $500 cash with NO warranty. This was a calculated risk on my part as it could've been completely bombed out & I'd have to eat it.....This gamble paid off as it's in near perfect shape for rebuilding.
The disturbing part is, It was on the very edge of the Sun Shell splines stripping out. Would've lasted 10-20,000 miles at most, Would've sucked for someone to put this in a AWD Escalade/Denali/Silverado SS & have it fail (Most likely out of the warranty period?)
