Test the 3rd Accumulator checkball, If it has minor leakage....Re-seat the checkball with a flat nosed punch with a couple raps with a small hammer from the valve body side of the case.

Use Plate GM# 24244053. https://www.amazon.com/ACDelco-24244...words=24244053

If your going to buy a Pump Kit....Get a 10 Vane.
Pump Slide Pins are usually worn on these. The Trans Go hi rev rings are pretty good as is the slide spring it comes with.

I don't like using steel boost valve sleeves in a 4L60E, I don't feel like going on a rant about some of Trans Go's mediocre consumer grade products.
Sonnax 4L60E-LB1 is a Aluminum Sleeve .490 Boost Valve, Comes with a 10% over PR Spring.....https://www.amazon.com/4L60E-Boost-V...ords=4L60E-LB1
Never mind the .500" advertisement....It's .490".

Use this spring along with the White servo cushion spring when using a 093/Vette servo......https://www.amazon.com/ACDelco-86811...o+servo+spring

Large (DX) truck Accumulator Valves generally cause a harsh 2nd gear when paired with a vette servo, Install a CX accumulator valve & sleeve from a Camaro/Corvette or put a lighter spring in it. Sonnax has 700 coded accumulator valve/sleeve/spring kits.

I use Borg Warner friction modules.
