Part No. 70239
Warranty Details (1 YR REPLACEMENT IF DEFECTIVE)
The B&M Shift Improver kits feature two options to recalibrating your 1982-1993 GM TH700R4/4L60 automatic transmissions. First is the HEAVY DUTY set-up, giving you firm positive shifts without loss of driver comfort for improved performance in all street vehicles. This is a great option for performance street driving or towing. The second is our STREET/STRIP set-up. Be warned, this will deliver firm positive shifts you will feel, along with easily chirping the tires when shifting somewhat aggressively. This setting is recommend for high performance street/strip use, or for competitive events when you want the hardest, quickest shifts possible from a shift improver kit. Note: Does not fit GM TH4L60E (electronic) transmissions.

I would buy this kit again
Verified Buyer -
Worked great, kit even included drill bits to enlage a couple of holes in the trans plate.
Bottom Line Yes, I would recommend to a friend
Feels more modern now
I put the stage 1 towing kit in my 700r4 in my Cadillac. It feels great. The job wasn't too hard but not too easy. Having a 3rd or 4th hand may prove useful when installing the valve body. Everything fit and moving parts move freely. Most importantly, the towing option is NOT rough. With the TV cable properly adjusted it feels great.
Great shift kit!

B&M is my go to performance parts company. This is the fourth transmission I have used this kit in. The only time I buy trans parts from a different company is when B&M doesn't have the specific part I am looking for.
Bottom Line Yes, I would recommend to a friend
