Frank, My copy of Supplement No. 1 (covering 1983 vehicles) specifies AMC/Jeep SAE 90 or 80W-90 Gear Lubricant (page 99, section 2B). This is probably the same as the change made in TB 2-1-82 (or TB 2-3-82), which was superceded by TB 2-5-82, mentioned in my other post on this topic. 1984 through 88 vehicles are covered in M.R.251, which specifies AMC/Jeep/Renault Manual Transmission Fluid Part No. 8983 000 000 for both the T-4 and T-5. (Page E-3) This is the lubricant that was known as "fish oil". Modern Driveline <http://www.moderndriveline.com/Technical_Bits/t5_history.htm> states that one should use SAE 75 gear oil for non World-Class T-5 (and by implication, T-4) transmissions, due to cold weather shifting issues with SAE 80W-90 gear oils. --Glen At 10:26 AM 9/9/2008, Frank Swygert wrote: >directly from 1982 TSM (83 was a supplement to the 82, nothing >different about lube in the supp): > >"The recommended lubricant for the SR4 transmission is SAE 85W-90 >Lubricant, API Grade GL-5.
