So when I finally got it back from the tranny shop, $125 bucks lighter, all they found was that my pressures are high (reason I brought it in), it shifts late and hard (again, reason I brought it in), my cable was not adjusted properly (I told him when I dropped it off), my lockup isn't working (duh, there's no wiring at all), and my cable geometry wasn't right (he couldn't explain
how it was wrong though). I have stock Qjet, cable and brackets. It's right on. Anyway, he proceeded to explain to me that I'd be farther ahead to just buy a rebuilt transmission than try to fix the one I have. But he was happy to sell me an ATSG manual at full mark-up so I could fix it myself since I'm "clearly mechanical enough to tear into one of those since you've already replaced the pump and valvebody. You should be able to figure it out" :roll: Basically, I paid for a diagnosis but only got a verification of my complaints. At least I got it back a week late and filthy from sitting outside. I hate being a customer.
So I finally got around to tearing it out and breaking down the pump and valvebody. The pressure relief valve was seized in my reman pump. Looks like it had some moisture in it while it sat on the shelf. Cleaned everything up and found no problems with the valvebody at all. There was one 3/4" tear in one of the separator plate gaskets. Put it all together and stuffed it back in the car. It's about 50% better. Still shifts too hard and late under light throttle. If I do a WOT run while manually shifting 1-2-3-4 it's perfect. It still acted like the pressure is too high all the time but I never hooked up a gauge to verify. I was pretty burnt out on it so I took a break for a few days.
After my break I spent some time at the yard yesterday pulling another 200-4r. Transmission #2 had a 30 day warranty and I was on day 28. So here's #3. It came out of an '86 Cutlass and looks really greasy but it's actually a coat of black paint. Probably safe to assume it was rebuilt in the past but at this point it really didn't matter. I pulled the pan and it had the usual residue and neglected orange-ish fluid.

Got transmission #3 installed. Left it completely stock and unmodified with it's matching used torque converter. All I did was drain as much fluid as possible and put in a new filter. I didn't even change the adjustment on the TV cable (it was dead-on). Fired it up and topped off the fluid then ran it through the gears on the hoist. Once I had positive engagement and positive shifts I dropped it on the ground and went for a drive. This thing shifted so nice! Put a few miles on it and brought it home to give it a bath. Next step wass to exchange the reman pump for another unit. After seeing the stuck valve, I'm suspecting that further moisture contamination is causing the slide to hang up. Then I'll throw #1 back in and try it one more time.
On a side note; Once I cleaned the rebuild paint off the tag on #3, I found that it was also a KC. The ink stamp on the valve body confirmed this. There was a lot of debris in the pan though. Put a few more problem free miles of in-town driving and was pleasantly surprised. Still shifted really nice. Pulled the defective rebuilt pump from trans #1 and took it back to the transmission parts supplier. Their "pump guy" is off for the week so I will get a call once he has a good unit for me.
So after 2 weeks went by and I still hadn't gotten a call from the transmission supply place, I dropped in on my way back from the machine shop. They had no idea what I was talking about :roll: . After getting the right guy at the counter I found out that nothing had been done AND they sent my core money to a random shop :roll: :roll: . They STILL didn't have a good pump on the shelf so now I get to make yet ANOTHER (my 4th) 2 hour round trip tomorrow when it's ready :roll: :roll: :roll: . I'm starting to think transmission guys kinda suck.
When the only tool you have is a hammer every problem starts to look like a hippy.
