About 3 days ago we received a call from my mechanic in regard to the price of labor and work. The torque tube you already know will be 495 from 928 International. The price of labor to change it out will be a nice $675 only! Not bad huh? Well it gets bad now...My mechanic said he has to send the transmission out for the leak. He spoke to his main transmission shop in regard to the leak coming from the torque tube and the guy said that he wants to overhaul my whole tranny and completely reseal it!!! <img border="0" alt="[grrrrrrr]" title="" src="graemlins/cussing.gif" /> There is nothing wrong with my tranny whatsoever, with the exception of the torque converter leak and the torque converter bearings! I would like to get everything all done at once but this guy wants to only rebuild the tranny if we have it sent out...what should I do? I don't want to spend $1800 just rebuilding the damn tranny <img border="0" title="" alt="[Eek!]" src="eek.gif" /> And I don't want to do the work myself. This guy is my best mechanic and he completely agrees with us about not having an already good tranny rebuilt.

Two ways I look at your situation.

1. Since you already have a rebuilt TT in route, get a price on a rebuilt tranny exchange as well. Compare the differences in price with your techs tranny guy. Maybe 928 Int will work a package deal favorable to your needs and monies

2. Depending on how many miles you have on the Transmission, just reseal it and have someone else do the work; contrary to your Techs Tranny Guy request to rebuild (what's the real motive).

How about getting our resident trans guru to tap in here. Hmm if Steve would only check in.

A rebuilt auto tranny from 928 international is ~$2K if I remeber correctly.

I'd hold my ground - if the leak is from the Torque Converter and there are no other problems with the tranny, I would thank the wrench(s) for their advice and insist that the work NOT be performed. After all, it is your checkbook - don't allow yourself to be intimidated.

If the transmission was performing well before the toque tube failed and there is only a front pump leak; then TELL the transmission shop all you what done is to reseal the front pump; front seal, o -ring ,gasket and pump bushing also ask them to check the torque converter hub for damage then for leaks by pressurizing it.

PS I answered your???? In your other TORQUE TUBE POST

THANKS John I was enjoying a <img border="0" alt="[cherrsagai]" title="" src="graemlins/drink.gif" /> when you called.

You need to look for the best total offer. If your friend only does the work in combination with a $XXXX rebuild that you don't need, and he is not willing to have anybody else do only the work that's necessary, well, then the deal your friend is giving you is not good.

I've had the torque converter seal done when I bought my car. They had to remove the transmission to do that, so it was costly, but not as bad as you state. The downside is that in the meantime my differential has developed a very slow leak. At this point it's only a drop every few weeks, but I start to wonder if it wouldn't have been better to reseal the whole thing when it was out anyway.

I am all for preventive maintenance, but not everything can be forseen. That and the high repair cost are reasons for me not to depend on the 928 as daily transportation. Remember that this car once was about $70,000+ - about four times as much as an econobox. So expect it to cost about four times as much to keep running (less, if you can do a lot of work yourself).

If that troubles you, consider geting a clunker for daily transportation and enjoy the 928 when you have the time. But don't make yourself a slave of the car - unless driving a 928 is the only goal you have in life...

 

Dont let him tear down your tranny. If you have a leak from the front of the tranny area that makes its way down to the "grate" (small grilled opening below the converter), my guess is its 1 of 2 things. 1) converter seal, which is EASY to replace 2) the gasket that seals the main pump (which is behind the converter when removed) . Both of these jobs you could do your self. Unless the tranny DOESNT shift right, grind gears..slip etc etc. I wouldnt let a tranny guy tear into it at all. hes looking for a quick buck IMHO.

I'm aware of how much these cars cost brand new. We bought an 85 928S off the showroom floor for about 61,000 in late 1984, when I was only 2 years old so 928s are not of a new ground to me. What gets me is that this jerkoff wants to rebuild the entire tranny instead of replacing one torque converter seal. Tony and the others are right. This guy is only looking for a quick buck. I will have to find a respectable transmission shop that won't shark a shark owner, but the car will goto my friend when the time comes.

This car is not a daily driver, it has been sitting ever since the problem erupted and we have 3 other cars to fall back on. I wonder if my mechanic will remove the front housing cover so that I can replace the torque converter seal and pump seal myself without even having to take the car to the shop. He doesn't have a press to do the torque converter bearings though. Unless there is an easier to do it without damaging the bearings.

Just by changing the front “SEAL” will not guaranty that the transmission will not leak from the front. The pump has three seals and one bushing. To do a quality front pump reseal, you should change all 4 parts.

Steve, everyone good news! After showing him Tony's page about replacing the torque converter bearings, he's convinced to do it himself. But we are looking at the reseal issue still. Does anyone know what the part numbers are from Porsche for the seals or does the dealer even carry them? How about 928 International or Devek? Do they carry the pump seal and that torque converter o-ring? BTW is the O-ring behind the torque converter after you pull the bell housing cover off??? I appologize for even more questions again, but we are now getting ready for this puppy to get fixed and all I need to do is get the parts!

All the trans parts are at the Mercedes Benz dealer........Front pump seals are not hard to do.

 

Sweet I found the torque converter seal at my Porsche dealer but the guy doesn't understand about the pump seal...must be a little new or just hired since I know everyone down there But does anyone have a blown up parts diagram of the torque converter and the seals, including the pump? Mike, sorry to trouble you again for another diagram but if you have it or anyone else does, email it to pors944@earthlink.net Thanks so much everyone for your help in this. My next update post should be when the car goes into the shop.

Since you're already buying the rebuilt torque tube from them, pick up the phone and call 928 International.

They can provide every part you need for the reseal, as well as provide real-world technical assistance.

 

Hear hear, Randy.

Get the work done with the right parts from the guys that have forgotten more than we'll know.

 

The o ring is located behind the pump body. To change the o -ring and bushing you need to remove the b3 piston, which is part of the pump. You need to compress the piston retainer and remove the ring. Once removed there are 5 torx bolts that holds the pump in place. When you remove the pump you can change the o rings and the pump bushing. You will need a bushings driver and foot press to remove the b3 piston. I do not recommend you doing the bushing and o ring your self. Find some one who is willing and able to reseal the front pump for you. You can not buy the bushing from Mercedes or Porsche. They only sell it with the pump body. It’s only available as an after market source. The pre 1986 A28 did not have bushings they used a roller bearing. If your tech thinks he can do the job with assistance he can call me and I will walk him or her thru the procedure. 845 567 0312

I wonder if 30 years in the transmission industries counts as real world technical assistance.

the parts that are needed

if the hub on your torque converter looks like this, it is bad.
