i just acquired my first 412 and would like to gradually rebuild the drivetrain. (as funds permit) The transmissionn currently runs and shifts well, but there are no records to confirm mileage or service history. That said, there is an 'Auto Trans Master Repair Kit PIONEER-752802' on the bay. Cost is roughly $240 shipped.

1) Is that kit sufficient enough to give a reputable tranmission shop for them to do a long-lasting rebuild?

2) Are there any other transmission components that should be replaced as it will be out and disassembled? ( torque converter seal, clutches etc.)

3) Are torque converters rebuildable? If not, are there any compatible ones from less rare vehicles.

Here is pic of transmission kit:

I don't think TCs are rebuildable, but a complete process for rebuilding the auto trans yourself has been posted in the Type 3 forum, I believe.

Yes.....TCs are rebuildable. ...just not at home. That said...a few have gotten better performance by using a bus TC for a higher stall point.

Look in the STF 411/412 forum. There are several complete rebuild threads. You need to be sure that you have the seal, o-ring and gasket that goes between the transfer case and final drive and you need to be sure you have the seal for the governor.

Also....and I definitely applaud what you are doing. Most people have no idea how well these transmissions actually drive when they are in perfect shape and adjustemnt.......if I were you.....I would get new differential and pinion bearings and do it all. The critical, part will also be to check fit and wear of the pump drive shaft into the pump and yhe wear and pumping efficiecny of the pump. If you can find a, new pump that would be a bonus. Ray

Great. Many thanks for the feedback. So, if I have this right...

1) I should invest in the kit that I posted above.

2) Check out the complete rebuild threads and, if possible, get new differential and pinion bearings to be safe.

3) See if I can hunt down a new pump; in the mean time check the fit and wear of the pump drive shaft/efficiency.

Hopefully, I captured all of it. Make sense? :?: :?:

Yes...and at one time...this place was one of the better sources for parts for these transmissions

Looking forward to this project. Hopefully, I'll be able to drive it through August on short trips as I collect the parts. The PO said the car runs beautifully. Can't wait until she arrives.

I edited and added to my links above. You also need the brake bands. I believe those are in the master kit and may be in limited supply. Contact Bulkparts above and e-mail for availability. They have a master kit generally with all the discs and the bands.

Roc Auto has this kit for $150.00

Look in my signature area under my builds. You will find a link for the rebuild process.

It's rebuilt and ready to go. The gentleman who did it was surprised that it had such little wear on the inside. I think that was great to hear. :?:

Cool!

There's a couple pics of an auto and important seals on my galley
T2 TQ in a T4/T3?? Have to change anything?
Would either final drive be very for aT3 auto with T4 engine

A T2 TQ will work in a T3 automatic as long as the engine is a T4. Also you can swap out T3/ T4 final drives, just as long as you swap out the governor. The governor and the shift body are a matched set. I do believe that the T4 final drive is lower (Ray?), but I did not feel an appreciable difference when I swapped mine out.

Hey sharkskinman.....sorry im so hard to get a hold of. On the road a lot.

Type 4 car:
wagons and some sedans had 3.91:1 final drive (11 to 43 teeth)
From Aug 1973 and Jan 1973 (differnt gear box codes) the sedan only.....had 3.73:1 fonal drive (11 to 41 teeth)

The type 3 had a 3.66 final drive (9 to 33 teeth).

Actually having a type 3 final drive auto in the car is a NICE improvement......but you will need a torque converter from a bus with a higher stall point to really experience it well.....or a tuned out (better thqn stock) 1.7 or 1.8....with more torque off the line.

I have had a type 3 box in my first 411 and it makes better second to third acceleration. ...if you are tuned well. However...with the stock converter....it was a little baulky off the line....tall gearing. I never had the opportunity or knowledge to know at yhat point in time that a bus converter with a higher stall point would help.

But I can tell you for surd that it will....because having the same final drivd in the 004 four speed....and the ability to slip the clutch a little....makes it night and day better off the line.

Also.....with a higher stall point converter in either type 3 or 4 final drive gearing....would make that damn throttle kicker plunger....unneeded. Ray

Where is the plug located on the transmission for the reverse lights? I just installed it in the car, but didn't really take note of the location. Thanks, -Ron

Its built into the gear shifter switches. under the bezel on the floor on the shifter. Ray

My bad, I meant the solenoid for the kick down. Where is the plug for that located on the trans??

The connector is on top of the trans gear case....just above the pan gasket joint.....on the left side..........just rearward of the dipstick tube and just before the joint between the automatic section and the differential section. Its a single male connector. Ray

Here is the connection point for the kick down solenoid. It is a hollow nylon type tube, with a male spade connector inside.
