Product Details

The Pioneer 747008 is a direct-fit automatic transmission modulator valve (also known as a vacuum modulator) designed as an OE-quality replacement for Ford, Mazda, and Merkur vehicles equipped with the A4LD and compatible automatic transmissions. The modulator valve is a critical component that senses engine vacuum and signals the transmission to adjust shift points based on engine load, ensuring smooth, properly timed gear changes.

Key Features:

  • Adjustable design: Vacuum range 7.5–18 in-Hg; EDA 1.03 in. with orifice restricted to .045 — no stripe designation
  • Single-area diaphragm construction for accurate vacuum sensing and shift point calibration
  • High-temperature oil seals for leak-proof, long-lasting operation
  • Performance-calibrated to match OEM transmission shift points to engine load
  • Exact-fit replacement — no modifications required
  • Undergoes end-of-line performance testing for quality assurance

Great price and quick shipper. Thank you.

Everthing went just fine thank you

Delivered as promised!

This company is super fast to get you your order! I ordered online and figured it would be at least a couple days or so until my order would even get processed. I think they overnighted it to me! The package showed up undamaged and sealed. Unfortunately, I may have to return the product as I am thinking I would like the spikes shorter but that is no fault of Thmotorsports. Hopefully their customer service is as superior as their ordering and shipping. At this point I would definitely shop there again and recommend them.

WAS VERY EASY TO PLACE AN ORDER, WILL WAIT FOR DELIVERY!
