Product Details

The B&M 35265 Shift Improver Kit is engineered to enhance the performance of GM TH200-4R automatic transmissions by delivering crisp, firm shifts while eliminating shift overlap and sluggish operation. This kit is ideal for street/strip performance, towing, and off-road applications where quick, positive shifts are essential for maintaining power transfer and reducing transmission wear.

Key Features:

  • Eliminates soft and sluggish shifts for improved acceleration and performance
  • Provides crisp, firm shifts that reduce shift overlap and transmission slippage
  • Easy installation with detailed instructions included
  • Perfect for street/strip performance, towing, and off-road use
  • Backed by over 65 years of B&M engineering excellence and quality

This shift improver kit modifies the valve body to optimize shift timing and firmness, resulting in quicker shifts that keep your engine in the optimal power band. The improved shift quality also helps extend transmission life by reducing heat buildup and clutch wear caused by excessive slippage during gear changes.

Ordered a sling to store my roof rack. There was an issue with the supplier which was quickly resolved by the Autoplicity staff. Great customer service -- most responsive I've ever seen.<br><br>Best prices around.

Super easy to browse web site and find the product I wanted.<br>The price was unmatched.<br>Shipping was fast and cheap.<br>Super shopping experience.

Great business, fast shipping. I received the item in about 2-3 days.

It may have taken a little while to ship, but it is definitely the best bang for the buck. I will definitely be looking here again for my needs.

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.

Excellent service with the actual stock on hand, shipment was made the next day and a tracking number was provided. I have tried 2 other online supply stores which don't know what they have in stock.
