Not really, a stock 4L80e will do like double or more power in stock form than a 4L60e. They are very strong stock.

A HD2 shift kit isn't a bad idea though. If you plan for tons of power with lots of abuse it may be worthwhile to purchase a vendors rebuild kit with upgraded parts, better torque converter.

I would do a shift kit . And yes a good converter . I have a circle d one . I love it . Besides that a custom cross member. I didn’t cut my driveshaft just added the th400 yoke.
And plug and play do the hardness I didn’t want to re pin it .
