Gary Lewis Posted December 5, 2018 Author Share Posted December 5, 2018 Boy that worked for me at Preston and later owned it had an Oldsmobile Vista Cruiser with the 330 V8 and ST 300. We spent about 45 mins one afternoon going through the switch adjustments. After it was done he drove it and came back and told me when he reached the pitch change it was like opening a 4 barrel. I built some ST 400s for Corvette owners who autocrossed them. On those, we just used a toggle switch along with a modified valve body (changed 2nd from a start in first to start and stay in 2nd like a Ford), the latter after the owner of the first one lost it in a corner on a high speed event when it decided to downshift to 1st on him. Trivia for you, one of the reasons those mid 60s GM products (Buick. Oldsmobile and Cadillac) launched so nicely in normal driving, at idle (closed throttle) the stator was in high stall, as soon as the linkage moved, it went back to low stall making the car move quickly away, at roughly 3/4 throttle they went back to high stall which acted almost like and extra low 1st gear. First, that's not trivia for me. I read all that in the hot rod mag's back in the day, and learned how to come off the line w/o going into high stall from them. Turn on the radio (AM back then) and tune to an unused frequency. Come off the line w/ever-increasing throttle and listen for the "pop" when the solenoid takes it into high-stall. Keep doing that until you get it into high-stall at about 20' of movement. That's the fastest launch. In my opinion the ST's with the Switch Pitch feature were good transmissions. Yes, only 2 speeds, but the torque converter made a big difference. So much so that they are now sought after. Link to comment Share on other sites More sharing options...
Ford F834 Posted December 5, 2018 Share Posted December 5, 2018 Jonathan - I can use it on my iPhone, but I cannot scroll to the right to see the transmission ratios - which you may not have been able to see either. Right? And, speaking of them and your questions: I have both the wide and close-ratio ZF's in already. Is there another one? T19: Kane Ellis has just asked about the 6:32 ratio on FB, so I need to dig back into this. Perhaps all of my literature will clarify things. Transmission ID: There are pages for that, so we may need to refer people there. Or, create our own? Hmmmm, lots more to do. Gary, I’m still having issues with the tool but it may be from lousy cellular data connection. Let me try again from a better spot before I cry foul. The ZF ratios you have are correct for the S42, but the diesel S47 model has different ratios. I don’t know how if all versions apply to Fords, but there are 3 different T18 ratios, 3 different NP435 ratios, 3 different T19 ratios, and 2 different Tremec 4speed OD ratios. I am also not finding much on the 3 on the tree gear ratios. I fully agree that there are other sites that do transmission ID nicely, and there is no need to replicate that. Same for general information and specifications. I don’t think it would be a bad thing to post up a quick chart with the ratios so folks don’t have to go on a goose chase to get that answer, but spending a bunch of time copying other websites is just that. Unless you have some better info straight from the literature. Edit: links to said good sites would be beneficial, however. Link to comment Share on other sites More sharing options...

Perhaps all of my literature will clarify things. Gary, I don’t know where F150Hub got their info., but it says that the 5.11 ratio T19 was only in 1983/1984 model years. It was mentioned a couple of times in the 1983 TV advertisements that we looked at a while back. I don’t know if that helps unravel the mystery of what years/applications got the 6.32 version, but I thought I’d point it out just in case... http://www.f150hub.com/trans/t-19.html Link to comment Share on other sites More sharing options...

But I still have some formatting to clean up. See what you think. And comments are appreciated. Jonathan - I'll try to research the T19 ratio question, but not right now. I found a latch at 4WD Parts that I want to consider for the bumper........ Link to comment Share on other sites More sharing options...

Saw one small glitch, you might have seen it also, lower chart MPH @ target RPM, AOD is listed twice in the headers, but mph seems to match E4OD ratios.

I found a latch at 4WD Parts that I want to consider for the bumper........ Gary, I finally did get the calculator to work with better internet. It is still extremely touchy... one touch wants to highlight a cell, and any additional touch jumps me to the bottom of the page. With some persistence I am able to get the cursor inside the cell. But for being on a phone I can’t complain. I have a couple of other suggestions.... one would be to add the NP205 transfer case since that is a popular swap/upgrade. The other might be to divide the automatic and manual transmissions into separate blocks. I know that will result in double the output sheets as well, but I think more columns are needed. In my experience the T18 and 4 speed OD are the most common manual units and both are missing, along with the T19. The last is a question more than a suggestion... but was there more than one gear ratio set for the C6? I thought I remembered a discussion on deeper C6 gear options on the diesel board but I might have misunderstood. Link to comment Share on other sites More sharing options...

I thought I remembered a discussion on deeper C6 gear options on the diesel board but I might have misunderstood. The C6 can be equipped with the E4OD main gearset (behind the OD unit) for a wide ratio build. This might require some throttle valve and governor tweaks to get the upshift points proper for a Diesel. I do know the Diesel torque converter is different, both in stall speed and number of attaching bolts and I suspect the friction elements (band and clutches) may be increased in size and number.

Jonathan - Here's a table from the 1983 Dealer Facts Book, which I'm using as my source. But tomorrow I'll see what else I can find with regard to another gear set for the T-19. Anyway, see what you think. I have the 3-speed, the T-18, T-19, and 4-speed OD added. It all seems to fit on one screen - on my computer. And I'd rather not go to two pages, tabs, etc as I think it is good to be able to compare a manual tranny to an auto. Oh, and the NP205 is on. I still have a lot of cleanup to do. But keep those ideas flowing in, y'all. Link to comment Share on other sites More sharing options...

It shows 3 different possible overdrive ratios for the 4 speed overdrive. The tables on F150Hub show .78 for everything. That’s why one should ~not copy and propagate every mistake out there on the internet 😬 Link to comment Share on other sites More sharing options...
