4L60E Internal Harness w/ Lock-Up TCC Solenoid, Anti-Bleed (2003-2006). For use with: TH700-R4, TH-700, 4L60E, 4L60, 4L65E, 4L70E, 4L70. OE Reference # 350-0061. For Units Without ISS On Stator.
The harness functions well after installation, but the delivery took longer than expected. Once I got it in, the TCC solenoid worked fine, and I noticed better performance overall. Just be aware of possible shipping delays when ordering!

Defective upon arrival
I was really looking forward to installing this harness, but it arrived with a damaged connector. I had to return it and search elsewhere. Super frustrating when you need it for your truck! Disappointed with the quality control, to be honest.

Transmission is back to normal!
After replacing the old harness with this Rostra one, my truck's transmission performance is back on track. The TCC solenoid made a significant difference, and I love the anti-bleed function. Installation was easy for someone who’s done it before. Totally worth it!

Solid Replacement for My 4L60E
I bought the Rostra internal harness for my 2004 Chevy Tahoe, and it worked like a charm. The anti-bleed feature is great, and my transmission engages smoothly now. Installation was straightforward, just make sure to follow the instructions closely!

Mediocre quality for the price
I installed the Rostra harness, but I wasn't too impressed. While it did fix the locking issue on my 2005 Silverado, the build felt a bit cheap. I expected a sturdier product for the price. It does the job, but I wish it was better quality.
