Got the shift kit installed as well as the new stator support. Then clean up the engine compartment.
That felt like the longest, most unproductive week of my life. I kept trying to make progress but it was just one interruption after another. After it was all said and done, engine ran great and looks okay. The transmission seemed to be wounded. The line pressures are all over the place. Some gears high and some low. Reverse seems pretty good. Won't build more than 220psi no matter what. Gauge check is important.
Got in contact with Superior and they believed the pump is weak. Since I had other jobs to do, it spent the night outside for the first time in probably 10 years.
So, here we are 10 days later. Finally got a chance to work on the Cutlass again. As I stated earlier, the guys at Superior indicated that my pump was weak. After trying a couple things I decided to just eliminate the possibility that I did something wrong and wanted to start from scratch. As luck would have it, that weekend was 1/2 off sale at PnP so I went out and yanked another transmission. It turned out to be a KC code out of an '86 Parisian and will be referred to as transmission #2 from here on. My research uncovered that it has one of the more desirable valvebodys. Brought it home, cleaned it up, replaced a couple seals, new filter and installed it. Completely stock and unaltered with it's matching TC. Lucky me! No second gear and slipping in 1 & 3. Pressure test revealed that it could not produce more than 120 psi. URG!!! Pulled it back out and spent a day trying to come up with a solution. The solution I came up with is to put a rebuilt pump in trans #1 and swap in my KC valvebody from trans #2. This would give me a rebuilt TC, pump, known good internals, and an unmodified valvebody.
Got it all swapped over and installed. Now it shifts into all gears with no slipping. But, it shifts hard and late. There is no passing gear kick-down function. It also has a very noticeable downshift when decelerating. A gauge check revealed that there was 275-300 psi almost all the time. It actually split the hose on my gauge in the middle of my testing. Cable adjustments made no noticeable difference. I gave up and decided it's going to a transmission shop for a professional diagnosis. So it didn't make it to the Pendleton car show. I ended up driving my dad's '64 El Camino instead. He drove the '68.
So when I finally got it back from the ****** 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 ****.
I ran transmission #3 for about a month before I finally got around to swapping transmission #1 back in. The current configuration is new converter, reman pump, KC valvebody. It's about 80% better now. Still has a pretty firm/late shift but MUCH better than before. Looks like the defective reman pump was to blame for most of it. I'm not completely confident in the current cable either. Acts like it's stretched or something. I might pick up a new one just to see if there's much difference.
To test it out I ran over the hill to the Wednesday night Beaches/PIR show.
My car ran great as usual. And, as usual, didn't get much attention at the show. I did catch a few guys trying not to get caught taking a closer look. Almost like they didn't want their buddies to see them checking it out. Great, my car's like a cute fat chick
