Installation Notes

Verify the transmission family and sun gear location before installation, especially on applications noted for THM200, THM200-4R, THM200C/MV9, or THM200/M29 coverage. Compare the original bushing dimensions and location to confirm the correct rear sun gear or reaction sun gear position. For best results, install during a transmission service or rebuild.
