Sonnax introduces new pump vane for Ford and GM transmissions

Sonnax highlights its line of pump vanes for GM 6T70/75 (Gen. 1), 10L60/80/90 (Gen. 1 and 2), Ford 6F50/55 and 10R60/80/90 transmissions. Sonnax touts this pump vane (part no. 124533) as a cost-effective alternative to replacing an entire pump rotor assembly.

Ford 6F50 and GM 6T70: Similar but Different

The 6F50 and 6T70 transaxles were developed as a joint effort between Ford and General Motors. Because this was a joint effort, as you can imagine many of the internal parts are very similar or almost identical. In this article we talk about the solenoid body and what is similar but different.

Pattern Failure

The definition of a pattern failure as far as transmissions go is seeing the same wear issue or broken part in every transmission of that type. This is such a case.

We have similar transmissions in two different car makes, the 6T70 from GM and the 6F50 from Ford. These transmissions are almost identical as far as the internal parts and pieces go, but they are controlled differently. The parts that fail in the 6T70 are different from those that fail in the 6F50, say the manufacturers.
