[82-UP] Automatic Transmission Bushing Extension Housing (Babbit) TH

When the extension housing bushing in an automatic transmission wears out, output shaft play increases and seal life drops fast. This is a single babbitt bushing designed for the extension housing position on 4L30E, 4L60E, Aluminum Powerglide, TH-200-4R, TH200, TH250, and TH400 (3L80) units, covering applications from 1969 forward. What sets this piece apart from generic replacements is the babbitt material spec, which matches the stock design requirement for this location in these transmission families.

Babbitt alloy is used in this position because it conforms slightly under load and provides a surface that works with the output shaft without scoring it. Installing a bushing of the wrong material here is one of the more common causes of repeat failures in extension housing rebuilds. This part addresses that directly.

REMCO has worked in automatic transmission parts since 1991. This bushing is pulled and checked individually before it ships. The part number is and the shipped weight is 1 lb.

This listing is for one bushing only. It does not include seals, gaskets, an Automatic Transmission Filter, a band, or any other rebuild components. If you are doing a full overhaul, verify the rest of your parts list separately. Before placing your order, confirm that your unit matches one of the listed transmission codes and that the year falls within the 1969-and-up range. If you are not certain of the transmission code, check the unit tag or cross-reference with the vehicle build records before ordering.
