Rebuilding Transmission Questions.

[65_valiant]

Going into my 65 signet. Stock trans as far as I know, would that be the 727??

Local shop quoted me at 1100 est, with me bringing it in OUT of the car and coming to pick it up, ill get a locked in price before committing obviously. I told them I wanted it to handle 400 horse and have a 3-3500 stall. The guy said something about useing a bolt in sprag?? I'm not familiar with the trans parts any deeper than valve body and converter goes.

Do you guys have any suggestions or tips i might mention to the builder? Street car with seldom track use, but I want to be able to rip on it and feel confident my drive line will hold up.:burnout:

Thanks in advance!!

1100 for just the trans????

Do it yourself. Buy some books/videos/guides and maybe $300 in parts on the high side.

Not hard to do!

$1100.00??? Outrageous!! Around here, my trans guy does them for $400, and it will handle 400 horses easy!! Must be in Cali, no?? Geof

That doesn't sound so bad if the parts are included in that quote, including a 3-3.5k converter and bolt in sprag

That is what your everyday suit would pay, yo know the guy who takes his car to jiffy-lube to get an oil change. A wrencher would tackle that head on with a master rebuild kit and a trans-go shift kit. 400HP out of a 904 is not hard. The convertor will cost you more than the parts.

for $1100 they better R&R it too. spend a few hours here and searching on the web and you'll find out all the trick parts to keep it alive

For those that questioned if that was parts included, yes they are. That was 1100 for an entire rebuild ready to install, minus fluid of course.

But it seems like the oppinion is that 1100 is on the extreme high end. I am mechanically inclined, no issues with that, but the time and zero experiance factor in as well.Are there any special tools i would need? I have all the hand tools i would need, but anything that would be needed?

Do yourself a favor and read this before you pull the trigger on a torque converter, scroll down for a summary if your a bullet point kind of guy:

Tools? Grab your pair of big c-clamps for compressing the clutch pack springs, and maybe pick up something you can make a slide hammer out of to pull the front pump. Maybe a small hook n' pick set for the small stuff.

Do download this, its the automatic transmission service guide, use it like a bible during the rebuild:

A couple suppliers for the parts are bulkpart.com and wittrans.com both have done me well.

I guess a few friendly tips would be:

Inspect all the bushings, plan on replacing the torque converter pump pilot bushing, the direct drum bushing and the tail shaft bushing as these are high wear items unless they look new. When it comes to that time, just take a hacksaw blade and cut the bushing length wise until you can tap it out. When going to re-install a new one, put the part in oven, at its lowest setting and the bushing in the freezer, grease up the part, and tap it in with a wood block over top of it.

Build on the tight side of specs, don't get in a hurry, and triple check everything before you put it back together.

Other than that, the a904 is one of the easiest, if not the easiest auto to rebuild.

Also do a search on this topic as it's been talked about plenty.

Enjoy!

I live in wichita, Ks. Actually only a few miles from Kansas International Dragway, didn't even think about it but I should go hit some of the guys with older mopars out there on a big race wekend and find out who they might use, if they'll give that info up that is...

For the clutch packs, just using c-clamps didn't work for me on a 904. I used a roll of packing tape and used wood quick clamps, any clamp will work tho. The tape roll size is perfect. Primative but effective.. hope this helps.
