Can TransTune fix any and all transmission shifting problems?
No – some transmission shifting problems can ONLY be solved by a transmission rebuild. If your shifting problems are being caused by sticking valve bodies, clogged oil pumps, or similar varnish build-up issues, you will benefit from a TransTune treatment. If your transmission has worn or broken components or leaking seals, then your only solution is professional repair. Using TransTune can actually help a professional mechanic to diagnose the problem by first eliminating any varnish deposit-related performance issues. Then if any true mechanical issues still exist they are more easily diagnosed.
