(888) 312-8812 Login SignupThe Allison Automatic Transmission Fluid Filler Plug closes the transmission opening used when fluid is added or checked during routine service. Its location distinguishes it from drain hardware and other case closures that serve different openings. The Allison 29530328 fits that fill point and covers the access once the fluid check or addition is complete. For technicians, the useful distinction is simply where the plug belongs and which service opening it closes.
