I have the transmission out on the ground, talked to A1 transmission about rebuilding, said between 8&9 hundred, seemed reasonable but then I remembered him saying he had rebuilt 14 in 2 weeks, also theres a broken piece off the body. 1. Could I rebuild a transmission. I worked as a mechanic at a papermill for 20 years repairing everything. 2 do to broken piece should I replace? Or let A1 rebuild it, I wanted a complete rebuild.
Do you

Good morning,

If you have never done one, I do not recommend doing this. There is a lot to rebuilding the transmission. There are hundreds of parts that all need to be inspected and tested. If you miss one of those failures then it will not work correctly.

Besides, you get a warranty if he rebuilds it. If you do the job, there is no warranty, just you.

If you decide to do it, I suggest a manual from ATSG. They have wonderful manual with all illustrations and instructions you need to do the job.

You will also need special equipment for the clutch packs to release the pistons for replacing the seals.

Give me a little time and I will get the information for you that I have in my information system.

This is just one example of a clutch pack that has to be build and air tested.

Roy

NOTE: The 42RE transmission uses four plates and discs for the front clutch. The 44RE transmission uses five plates and discs for the front clutch. The front clutch retainer is not interchangeable between the 42/44RE transmissions.

DISASSEMBLY
1. Remove waved snap ring and remove pressure plate, clutch plates and clutch discs.

2. Compress clutch piston spring with Compressor Tool C-3575-A, or equivalent. Be sure legs of tool are seated squarely on spring retainer before compressing spring.
3. Remove retainer snap ring and remove compressor tool.
4. Remove spring retainer and clutch spring. Note position of retainer on spring for assembly reference.
5. Remove clutch piston from clutch retainer. Remove piston by rotating it up and out of retainer.
6. Remove seals from clutch piston and clutch retainer hub. Discard both seals as they are not reusable.

ASSEMBLY
1. Soak clutch discs in transmission fluid while assembling other clutch parts.
2. Install new seals on piston and in hub of retainer. Be sure lip of each seal faces interior of clutch retainer.
3. Lubricate lips of piston and retainer seals with liberal quantity of MOPAR Door Ease. Then lubricate retainer hub, bore and piston with light coat of transmission fluid.

4. Install clutch piston in retainer. Use twisting motion to seat piston in bottom of retainer.

CAUTION: Never push the clutch piston straight in. This will fold the seals over causing leakage and clutch slip.

5. Position spring in clutch piston.

6. Position spring retainer on top of piston spring. Make sure retainer is properly installed. Small raised tabs should be facing upward. Semicircular lugs on underside of retainer are for positioning retainer in spring.
7. Compress piston spring and retainer with Compressor Tool C-3575-A, or equivalent. Then install new snap ring to secure spring retainer and spring.
8. Install clutch plates and discs. Install steel plate then disc until all plates and discs are installed. The front clutch uses 4 clutch discs and plates.
9. Install pressure plate and waved snap ring. Front clutch clearance should be 1.70 to 3.40 mm (0.067 to 0.134 inch). If clearance is incorrect, clutch discs, plates, pressure plates and snap ring may have to be changed.

I'm sorry, I have a 46re, I must have typed it wrong. I think I'm going to leave it to a professional. A lot of parts in there. I was going to haul it in the back of a car. I've read where they weigh 250 pds. Now just got to get it in there. Thanks guys. I'm still waiting on engine which is worse than first thought and now $2,200.00 plus converter for transmission. Uhmm, hope we get another stimulus check. ; ) Thanks guys

Are they charging you $2,200.00 to bench it without installing it?

That is very expensive.

Yes, plus the converter. What is the going rate for a complete rebuild, I had a guy that would do it for eight to nine hundred. Also it was doing fine except for a whine going down the highway. Like urh, urh, urh. I thought that was rear end because when I put it in neutral it stopped, but when I pulled motor I found chips of housing metal, it came from this round part of transmission housing. Being a 1979 I thought I should rebuild. The fluid is changed every other oil change. Should I rebuild, check rear end?

The $2,200.00 with a converter and installed is in line.

If you present the transmission out of the car, $950.00 with a converter is in the ball park.

Okay, sounds good. Not sure if you seen the pic but I didn't find all of the metal so it had to go through with fluid or fall out'

Check with a shop that does transmissions. The majors will get big bucks. I am all about supporting small business.

Yes, that was the first shop I checked with, the other is an independent but also very well known for building transmissions for race cars, the same as the guy rebuilding my engine. He builds 1,000 hp motors for race cars that another guy I know runs.

With him rebuilding your engine, he should help you out. Do not be afraid to go somewhere else.

This is a transmission guy that my engine guy recommended. Lol, I don't trust anyone working on my stuff. I will call him in the morning. If he doesn't come down I'm either going to take it to the first guy or try to flush it out and put it back in. Only thing I don't understand is what broke that piece off and is that what was causing the noise I heard going down the highway? I'm sending a pic, blew it up and half of the inside of that hole is missing.

That is case damage. You cannot repair that part. You will never get back the strength back on the part.

That, I believe is the mounting for the starter.

That breaks when the starter kicks back and all the torque breaks it off.

I would check with the dealer. They will sell you a new remand with a warranty. The only thing is that you will have to pay the core value.
