Opinions on B&M Shift Improver Kit
Has anyone installed this on their 4L60E? If so, any opinions? I was looking at the Heavy Duty kit to just firm up shifts a bit. Don't need the Street/Strip.
Also...is it worth getting a deep pan? I'm just looking to improve things a bit better.

B&M has a shift improvement switch that accesses the different tables for shift firmness.
Does it work ? I don't know. I just remembered that I saw it in my wanderings around the web

in the Jet software tables, there are Normal, Performance and Manual mode entries

Transgo kit is the best for the 60E to me. I use Superior kits on some units I build, just varies upon what all is included in the kits.
Pick up the aluminum accumulator for 1-2 and forward. Use the lightest settings on the VB plate to start with upon install and in the 1-2 accumulator (aka NO WASHERS)...one can always increase shift firmness, trying to pull it is a pain in the ***. I advise buying the HD plate from Transgo too. Sonnax has a nice HD shift valve, unsure if retros back to this early of a trans. You will have to research it.
https://transgo.com/product-details/4l60e-hd2/ Yes, using that gold colored shim for the 1-2 shift servo helps clean up the up and downshift of the unit. It is a ***** to get in fully and lined up. I do like Superior's billet OD servo, turns it into a crisper shift and quicker downshift.
Last I did was this spring on my '01 Burb, 4L60E but it was a PWM converter lock. Now it is just ON/OFF. Far better. Sure, pick up a fresh filter while there and a quality pan gasket. Late units had a drain plug stock and were one quart deeper. Unsure if clears a car lowered, I plan to test from a core 65E I have laying around on my 700R4. Same pan/gasket. 99-02 trucks for sure had it.
Hope it helps, let me know if you have more questions.

I second the Transgo kit. The only thing B&M does right is shifters. It seems like everything else is pretty poor quality. Transgo and Sonnex both have a great reputation for transmission performance parts.
