Product Details

The Standard Motor Products TM34 is an automatic transmission vacuum modulator designed to replace worn or faulty factory units and restore proper transmission shift performance. This precision-engineered component regulates transmission shift points based on engine load, ensuring smooth and responsive gear changes.

Key Features:

  • Performance-calibrated to match transmission shift points to engine load for optimal shifting
  • Nylon-reinforced diaphragm provides extensive durability and tear-proof operation
  • High-temperature oil seals ensure proper fit and leak-proof performance
  • Steel modulator valve construction with gold iridite finish for corrosion resistance
  • Direct replacement for OEM specifications

The TM34 vacuum modulator uses engine vacuum to sense load conditions and adjust hydraulic pressure within the automatic transmission. When the modulator fails, symptoms may include harsh shifting, slipping gears, poor fuel economy, or transmission fluid leaks. This replacement unit restores factory-specified transmission operation and shift quality.

The order was easy and shipment was fast.They had what i was looking for at a great price.

Autoplicity was plenty cheaper than competitors for the springs I needed. I was shopping around and left the website after beginning a transaction and they sent me a coupon for 25% off shipping if I would return and purchase from them, which was cool. Unfortunately the coupon code didn't change the price and I didn't receive 25% off, but it was still cheaper than others.

Quick

Great product! Don't even think about another battery hold down - this one is strong, light and has the good looks to boot. Saved over $30 on it too.

The service Autoplicity provides is top notch!! Shipping is fast, customer service is very helpful and the products are great!! Most of all, you cannot beat the prices. I would recomment Autoplicity to anyone looking to save a little money on those must have auto parts!!!

Best price I could find anywhere. Almost 10% less than my typical sources and the item shipped in less than 24 hrs.<br>
