TH700-R4 4L60E [82-UP] Automatic Transmission Bushing Case (Babbit)

When the case bushing wears, shaft play increases and the surrounding bore takes damage that no seal can correct. Replacing this single babbitt-lined case bushing is the straightforward fix for TH250, TH350, TH700-R4 and 4L60E automatic transmission units built from 1982 onward.

What sets this part apart from a generic replacement is the babbitt lining. Babbitt is a bearing-grade alloy that conforms slightly under load, maintains a closer fit at the shaft and distributes stress more evenly than a plain cast bushing. That difference matters on a unit that runs under sustained hydraulic pressure and heat.

This listing covers one part and one part only: the case bushing, SKU, shipping weight 1 lb. There are no seals, no gaskets, no clutch discs, no steels and no Automatic Transmission Filter included. If your rebuild requires those components, they need to be sourced separately. Check your parts checklist against what this listing contains before placing the order.

At REMCO, operating in automatic transmissions since 1991, each piece is pulled individually and verified against the part number before the box is closed. A parts list ships inside the package so the technician can confirm receipt at the bench without guessing.

Before ordering, verify two things: the transmission code on your unit is TH250, TH350, TH700-R4 or 4L60E, and the vehicle model year is 1982 or later. Those are the boundaries of this application. If the code or the year falls outside that range, this is not the correct part.

• Restoring proper shaft alignment at the case helps avoid premature wear and transmission failure on TH250, TH350, TH700-R4 and 4L60E units.
• This listing is for the case bushing only. It does not include any seals, gaskets, clutch packs, steels, Automatic Transmission Filter or additional bushings. Review your full parts list before ordering.
• A babbitt-lined case bushing holds tighter tolerances than plain cast replacements, reducing play at the bore and extending the service life of the surrounding components.
• One piece: babbitt case bushing. Shipping weight is 1 lb. Part number. Selected at the bench to match the application before the box is sealed.
• Before ordering, confirm the transmission code stamped on your unit matches TH250, TH350, TH700-R4 or 4L60E and that the model year falls within the 1982-and-up range.
