Uhh, I hate to sound like a dork, but I scrambled some of my torque convertors and I have a 200 R4 leaving this week. Sooooo, if it fits the trans is it the right convertor? Or will others (350 400) slide on too and mislead? I'm almost 100% sure I have the right one on there, but some assurance would be nice.
Not positive but I think the stock converters had a 5D stamped around the edges.I have an 84 t-type core,and that's what it has.
Dan - This might help......courtesy of gmtuners.com -------------------------------------------------- GM RWD Torque Converters Starting 1980-up, GM used a 4-digit ID sticker located on the converter body to help identify it. Below is a guide to help decipher it's meaning. 1st Digit (application trans) B -- THM250C, THM350C C -- 200C, 2004R, Pre-1984 1/2: 325-4L & 700r4 D -- 1984 1/2-up 700r4, 4L60, 4L60-E 2nd Digit (approx stall, depends on engine) B -- 2025 rpm C -- 2075 rpm E -- 1654 rpm F -- 1611 rpm G -- 1397 rpm H -- 1397 rpm K -- 1211 rpm L -- 1654 rpm 3rd Digit (Clutch Assembly) 3 -- Poppet Valve 7 -- Poppet Valve 9 -- Poppet Valve A -- Red (pre-96) A -- Carbon (96-up) B -- Static Open G -- Carbon Fiber H -- Red (pre-96) H -- Carbon (96-97) H -- Woven Graphite (98-up) L -- Carbon Fiber N -- Woven Graphite P -- Woven Graphite 4th Digit (Body Mounting) C -- 3 round lugs, gas engine D -- 3 round lugs, diesel engine E -- 6 round lugs, gas or diesel F -- 3 square pads, gas or diesel G -- 3 square pads, gas or diesel If there is no ID tag, there might be a number or letter stamped between the dimples of the impeller on the converter body. 4 -- 1211 stall 5 -- Medium or high stall (depends on stator) 6 -- 1397 stall 7 -- 1654 stall C -- 2075 stall H -- 1397 stall K -- 1211 stall L -- 1654 stall
