I bought this transmission 4 months ago. I was going to put in my 65 mustang. Here is the information on the T5 World class V8 T5's V8 Mustang T5 commonly found in 87-95 Mustangs. T5's feature only OEM Tremec Gears, new synchros, new 1-2 slider, new Timken Premium bearings, shift-fork pads, small parts kit, and seals. All transmissions are cleaned, hot tanked at 200 degrees for 2 hours. Every T5 gets an all-steel bearing retainer installed as well, free of charge. Accept only the best for your hard earned money! Don't waste your time buying from other sellers who use aftermarket gears to increase profits, demand quality.
