product not machined correct

November 02, 2013
Transmission mount is a good poly mount. The only flaw is the bolt holes tapped in to the mount were tapped crocked. They will work, but are border line. I am sure they are not made in the USA. I did not contact speedway about them. Like I said they are borderline.
Pros:
  • good poly mount
Cons:
  • bolt holes tapped crocked
Yes, I recommend this product.

Problem-solving 700R Trans Mount

June 26, 2012
The 700R4 trans I was installing in my 46 International hotrod pickup came out of an 88 2WD Suburban and had a rear mounting pad with one bolt, most of the after-market crossmembers had 2 bolt holes so this mount with 2 bolts worked great. The old mount was kind of ratty anyway, so it was a no-brainer to buy the new one.
Pros:
  • Durable
  • Easy To Install
Yes, I recommend this product.

It is a great product for cars that do both street and strip duties....not as rigid as solid mounts but still strong enough for drag use...
Pros:
  • Tough enough 4 racing

Part # 91025820 This mount will work with most GM transmissions and the slotted holes will work with mount centers of 3 ¾” up to 4 ¼”. The cross member in some cases may require minor modification depending on the application. As opposed to the original mounts with two threaded holes this mount has 3 for more versatility.
