Alloy corrodes so these rads don't silt up but the alloy particulates form a solid clump blocking the RAD and often the STAT, the STAT however is designed to always stick in the 'open' position. The solid matter in mine was probably the use of non-HOAT and not using distilled water, so no recommend inhibitors. I did mine old school .. .. .. - car running, heater full belt on manual not e-setting - switch engine off - remove cap from expansion bottle, insert garden hose - slack off bottom hose a little - switch engine on, heater full belt on manual not e-setting - regulate the clean water in speed [expansion bottle] to the [bottom hose] dirty water out - drink coffee - when the rad & matrix is fully clear, engine off, allow 10 pints [ish] to drain from the bottom hose - clamp the bottom hose, fill with - a gallon of hoat and a gallon of distilled - burp and top up the expansion bottle

I had same problem on mine. After ripping my gearbox out and having it in million pieces turned out to be...... Torque converter failed. Reverse and 1st gear hesitatation are generally signs of torque converter failure. Unfortunately it's whole gearbox rebuild as generally more stuff like snap rings break due strain etc from failing torque converter. I successfully rebuild mine. Lots of info available from helpful American's on YouTube but not a job for faint hearted.
