I took the clutch tool pictured below and added the extra threaded rod on the bottom to get around the issue that Andrew found with it not being long enough to take out the 3rdinput clutches. Step 5 Lets Get Started. Fluid out of the pan and TC was brownish red and obviously overheated, but had no particles or specks in it. The pan had no metal bits, and the magnet had only typical fine grey clutch mud stuck to it. Cracked open the filter with a hammer and chisel Only some fine clutch mud, no metal particles. The third pic shows some black flakes stuck between the felts. I know what that is already, but Id be getting ahead of myself wink Step 6 OK, so Ill go through the book step by step, with my inspection notes and pics on the dismantle. I did not get a picture of everything, so if anyone wants me to go back and snap a photo of something, let me knowTorque converter JTFM 2. TC. Looks OK on the outside and in the teeth, but the bearing has some nicks in it. Probably best used as a core for a reman. Reverse Servo OK. Forward Servo OK. Pan OK cleaned up great. May investigate getting a drain plug welded into it. Two M6 bolts missing, but threaded holes in case all OK, and can get 2 replacement bolts from Intense. Pan Gasket in excellent shape after cleaning, and can be reused. Oil filter No alarms see previous posts. Accumulator assembly and 2 1 Band Servo OK. After I get new piston seals out of an Overhaul kit, Ill probably swap this unit in its entirety into the current trans and swap in the current trans unit with Thrasher shift kit already installed. Control Valve Body Cover Side Cover OK. Very grimy, but cleaned up fine. Gasket in great shape after cleaning, and can be reused. Had a W body specific mount bolted to it, will probably give away or sell mount. Wiring Harness Screwed that puppy up all the little plastic retaining clips to the solenoids were very brittle, and as careful as I tried to be I broke every last one of them This harness will find use as part of a solenoid test apparatus. I bought a replacement used 1. EBAY seller I have bought good parts from before it checks out OKStep 7 Oil Pump Removed but not yet disassembled for inspection I bought a spare pump for 1. Club. GP, and will use whichever looks better inside. Step 8 Control Valve Body Assembly Removed and prepared for inspection Checkballs, case cover pin, separator plate, pressure switch, etc. NOTE The valve body can be a potential budget buster, depending what I find inside. Step 9 Oil Pump Drive Shaft Teeth at pump end OK, but teeth at TC end are badly worn Shaft on right from this trans shaft on left cost me 1. I bought used off Club. GP. Both are actually not so good will probably buy a 4. GMPD pn 2. 42. 09. Step 1. 0 Vehicle Speed Sensor OK. Output Shaft Differential Extension Housing OK discussed in earlier post. Manual Valve Link, Oil Dam, Input Speed Sensor OK.
