if you're getting noise while standing still and in park/neutral, then it's not the differential (because nothing inside it is trying to move around under those conditions). so then it has to be something that's always moving, like the flexplate, pump or other internal tranny part.

It isn't exactly easy, but it is not rocket science. You do not need a welder or torch - you can unbolt the exhaust where it connects to the headers and take it out as a single unit (if you live outside the rust belt - otherwise you may need to torch the bolts off at the headers) and then at the other hangers on the way back. The driveshaft will just about fall out of the car once unbolted. The half shafts are easy if you use beav's advice to remove the 3 bolts underneath instead of prying out the balljoint. The tranny will come out pretty easy once you remove all the bolts, electrical stuff, starter, hoses, and then jack up the front of the engine. It is very heavy though, and my technique of balancing it on a regular floor jack with some short 2x4's to support it will end up with the tranny falling out and landing on the garage floor once it slides off the mount studs and its weight shifts. Not a good idea. Rent a tranny jack.
I had to jack the car up, put it on jackstands, then use 2x4's with the floor jack to get it higher and then set it up again on the stands. The car has to be pretty high for the tranny to clear the bottom of the engine when dragging it out but I only have 4 standard 2 ton jackstands and it worked - not sure how high they were but I had the front of the car jacked as high as they would safely go.
With months passing since I did mine the memory of what a pain it was may have dwindled some but I would do it again in the garage if I had to.
The satisfaction of completing it yourself is priceless.

I would think that if it were the diff, you wouldn't hear any noise when in park or neutral, since it wouldn't be getting and power. I suppose you could jack up the front end and turn one wheel and see if the other wheel moves. If it moves, then the result is inconclusive. If it doesn't, well then, you've narrow down the problem somewhat.

I have pulled and replaced the SVX tranny twice on jackstands in my garage (if you have to know - I screwed up the first time by incorrectly installing the torque convertor).

I found a motorcycle jack to work wonderfully. I can't remember the brand, but I got it at Sam's and it lowers to a height of about 1.5 inches. It has two flat arms, about 3 inches in width, that are long enough, and spaced such that they support the tranny across the front/back edges of the pan. At maximum extension it's just about perfect for putting the tranny back given the height of my jackstands. The jackstands by the way are only tall enough to get the tranny in/out if if I take off a tire and push down a little on the bellhousing section to clear the subframe enough until it's safely in the hollow behind the engine. As another hint, I used two nylon strap-clamps to hold up the front of the engine. Strap-clamps are those things normally used in woodworking to keep ackward shapes in place while being glued up (I used two as insurance - not actually using the second until I got scared just watching the engine sitting there with just one thing preventing my radiator from being toast too). Ran the straps through the dogbone, over the fuel injectors, and closed the loop through the eyelet by the alternator/A/C compressor.

Just about the only other tools needed are a metric socket & wrench set. Oh, and for the jackstands - on the front I put them under the subframe by the engine so the tranny could roll in and out on the motorcycle jack - which has built-in rollers.

Beav's hint about the 3 bolts on each side was invaluable in shortening/easing the job. Oh, and I had the benefit of an electric 1/2" impact wrench for help on getting those and the exhaust studs loose.

The hardest, or maybe most tedious, part of the job for me was getting the 4 bolts connecting the TC to the flexplate off/on.

My second time assembling I went from trannny sitting on the jack next to the car, to driving away in about 2 hours.

Nick,

Took off the other head last night and checked it for flatness and possible gasket failur points. Couldn't find anything out of the ordinary so I'm putting it back together and taking my chances. The water pump may still be bad. It's coming off tonight.

So, what I'm saying is I'm going to re-assemble mine, but if you want to try and do a trans removal on the junker let me know as soon as possible and I'll rent a truck/trailer to get it to my house. Once there we can remove yours and replace it with the junkers, if it's OK (big ????? on the condition)

Todd

Todd,

I'm glad to hear that your engine looks okay. I hope your car goes back together without difficulty.

As for the wrecked car, I'm willing to try if you are. I will look into how many miles of towing I really get from AAA.

Oh, and just in case, I'll call you at your office around noonish.

I'm wondering whether I'm looking at a problem with the torque converter, and not the trannt or diff.

If you replace the whole schmear (with the tranny from Todd's junker), it really shouldn't matter. . . should it?

(Or, do you have a coloquial use for schmear that I don't know about like you do for "cattywhompus?" )

Well, we don't yet know whether that tranny is viable. It's so wrecked that I'm concerned the tranny case may be cracked or otherwise damaged.

I don't know how it was hit, but what if the tranny was shocked through the drive shaft - would that damage the case or at least some seals? I don't know. We're going to take a look at the car soon to determine whether or not it's even worth trying.

Here is the pic we spoke of earlier today. Find the rear engine lifting hook and go towards the center of the engine.


Tried to post pic here in message but couldn't. Wierd. I'll try to put in in my locker.

I talked to Nik on the phone a little while ago and he asked me to post this since he won't have internet until tomorrow.

His transmission works fine in forward and reverse until the tranny warms up. he drove it up and down his street until about 5 minutes in then it made the noise and tranny just slips.

You guys have any ideas what he could try?

So it works okay when the fluid is cold. Someone else suggested the cooler may be plugged. Pull the lines off, one at a time, the one to the cooler, the one after the cooler, and see if fluid comes out.

The good news is that it isn't any of the gears.

I doubt that the cooler is plugged - I just installed a B&M cooler, taking the stock out of the loop entirely. If that cooler was going to cause something, I imagine it would have during the 300mi of commuting the week before my 1,000mi road trip.

Still, maybe I should just unplug the B&M, hook up the stock cooler, and see what happens when I run like that.

Ironically, the whirring noise I hear after the car warms up sounds JUST LIKE a power steering pump under strain. So maybe the pump just isn't getting the volume it needs...

Grasping at straws?
