Allison Warranty Issue

[TH]

Has anyone had any experiences with their Allison transmission warranty work being denied :eek: because of the use of non-stock tires...even relatively small size upgrades to 285s? :confused:

It is GM's policy to not do any diag work with a allison trans problem when non oem size tires are used. Best bet is to put the stockers back on and take it back in.
