So, now for the next few days, I’ll be tearing this down and doing a full rebuild, bushings and all, plus the addition of better frictions and bands, and a shift kit.
I’ll take pictures all through the process until I have to poor girl back on the road and not leaving a red streak of transmission fluid behind her where ever she goes.
Still waiting on the torque converter to arrive any day. All I have to do is reuse my bell housing and some linkages.
I bet the UPS guy has a hernia! Just kidding of course. I tried to give my UPS guy a beer after delivering a “box of anvils” to me. Turns out they get fired on the spot if they get caught with a beer.
Where did you get the cart? That looks perfect for parts cleaning.
Its a Snap-On cart. its one of the many things I acquired from a friend who used to be a mechanic and owed me money. I have two of those carts, a huge Mac tools roll around tool box, and a twin post lift that is waiting for a bigger shed to be installed in.
The guy didn’t owe my a huge sum of money, just many medium unpaid loans where I got more and more of his stuff when he couldn’t repay which erased the debt and allowed him to “borrow” more money as need be.
Overall, it looks like the trans was somewhat neglected, but not really abused. All the guts, minus a few thrust washers, the low/reverse servo and the parts being replaced by the rebuild parts I bought look like they can all go right back into service after cleaning and soaking in trans fluid a while.
That was it for yesterday. Today will be individual component cleaning and inspection and running to Transtar after I figure out which thrust washers I will need.
Great pictures. I have seen much worse rebuild and work like new. Keep up the great job. Be sure to soak the clutch discs over night in transmission fluid.
I’ve purposely been trying to say “transmission” or “trans” in place of “tranny” just to avoid that mental image, lol.
I am at a stopping point at the moment. I have to wait till Monday to order the thickest snap ring for the forward clutch pack. My clearance is already at the far end of the allowance, so any wear will put it out of spec and I can’t add another plate to the pack to take up slack, so that is my only option for now.
After that, the rest of the reassembly should go smooth. The end play of the input shaft should be between .008" and .042", and before tearing mine apart, it was about .085", so hopefully the thicker thrust bearings should take up that slack when its back together for more measuring.
Hopefully Transtar can get that snap ring to the local warehouse asap.
The discs get a little thicker when they soak in ATF. Did you soak them first? If the spec you have is for a dry disc then disregard what I am telling you.
The trans will get some more work done tomorrow. I had a delay of game with another project. Our boat has been under renovation. It has gone from this:
The 3208 Cat that’s in the youtube video. 375HP at 2800 RPM. We built that cabin from scratch out of 2" thick foam board with a LOT of fiberglass on it.
Okay, finally got back to the transmission today.
Got all the guts reinstalled, valve body rebuilt with “reprogramming kit” from Transgo, all the air checks done and the bands and clutches are working like they should. Got the final assembly wrapped up as much as can be without pulling out my current trans out to get its bellhousing and shift linkages to put onto this one:
Installed the filter, put a magnet in the pan, installed the AN fittings to run hoses instead of hard lines to the cooler(s), adjusted the bands and put the locking nuts on the adjuster and put the modulator valve in after this picture was taken:
The wrenches on the front were put on the bolts to take up the slack that the bell housing usually does so I could torque the pump bolts and check end play.
I luckily guessed correctly on my select fit thrust washers. End play should be .008" to .040" When I started, the trans had .080" end play, and when I got it put back together today, it measured out to .015" on the first try. So, I have room for things to break in, the new thrust washers to wear down a little, and it still be in spec.
That little Makita 18V impact driver is a life saver for disassembly and reassembly. With the variable trigger, you can snug up bolts until it stalls out, but before it starts to hammer like an impact, and that is below any torque spec on the trans. That way you can come back later with the torque wrench and make sure it is all correct.
It is supposed to rain and get cold again tomorrow, so that will dictate if the current transmission comes out of the car tomorrow.
