Let me introduce my car and st up to y'all. I got me a 1980 bowtie Camaro but it has a 440 big block with A-727-B transmission. The tranny is a short snout so I assume its from a truck. Well I was driving it and heard a huge popping sound towards the back and was wondering what was it that we heard. Now when I drive it will a little bit and then slip. It will go nowhere. Turn the car off for a min or 2 then will go a little bit. Any ideas what's going on it what happened? Checked the fluids and its full and not burned up.

Hard to say. Slippage and shift problems can be quite a few things, some cheap to fix. But loud noises and breakage are usually "serious."

the upside is that TF transmissions are one of the easiest to rebuild there is, period

You can download several shop manuals which have troubleshooting info:

and you can download what is essentially the transmission section of the shop manual here:

Consider buying the excellent book on the subject by Munroe


and on YouTube there is a series of about 20 videos on rebuilding one


Now, I don't know how in InternetExploder, but if you get Firefox, which will run in WhineHozed, you can get a plug in / add on called "download helper" as well as some other ones, "Flash video downloader" and either of these will allow you to download these videos and save them for later

If you dance around the www a bit, there are some guys that are VERY knowledgable, and you don't need many special tools. If you are "handy" you can build the compressor you need pretty easily.

I would start by checking the rear differential before the trans. Then drop the trans pan for a look see

Thanks for the reminder. Google "bolt in sprag"

In case of a rear axle or U joint failure, this can damage the "sprag." If this is not fixed, real problems can occur. Also Google up how to properly handle burnouts in hot, high HP torqueflites

I am talking about the spider gears in the rear end ! Maybe broken ??? The sprag is usually damaged by doing a bad/ incorrect burnout

440roadrunner

I know. But damage to the sprag is COMMONLY caused also by breakage in the rear axle. Whenever a U joint, rear axle, or "any" breakage is experienced, the transmission should be checked for rear sprag damage.

as all ways the trans experts here are great. but thats not me. so could 440roadrunner tell me if this is right. i think i heard that at the track you have to be care full how you do the burn out. so the trouble you listed doesnt happen. i think i read that.???

440roadrunner

The problem is several, and I'm no expert. Part of the problem is the weight of the rotating drum in the 727. The same thing can happen in a 904, except they "generally" can't explode like some of the 727s have. Just google "exploding torqueflite."

Also some of the GM trans suffer the same fate.

I just diddnt know where to start looking. If it is the rear end or the tranny? It has a gm rearend

TVLynn

GM rear all the more reason to check it...

camaro440

I looked and there is no linkage going from the carb to the transmission linkage

camaro440

Looking for another 727. It has a short tail shaft. Does anyone know other than motorhomes what other had 727 shirt shafts

moe7404

i had a new 1977 dodge 100 club cab, long bed, i think 149" wheelbase. 318 727. it had a short tail housing. and two piece drive shaft. i dont know if they had only 1 length short housing, but i think they had only 1. NO linkage to the trany? please dont tell me they have HOSE for fuel line!!! does this cat have a death wise?

camaro440

I'm looking for a big block shorty 727. That's what I have found that trucks and motorhomes have them. Any aftermarket company sells built shorty?

Coronet 500

Having the kickdown linkage is critical unless it's full manual.

I would definitely check the rear axle first. Have someone lay down and watch your diveshaft when you try and accelerate.

moe7404

i think the short housing by itself 727 is the same whether "A" or "RB". so i think you can mix and match. of course the inside parts have to match tail housing length. cause i sold a small block 727 short to as guy for a "RB" 727 trans.

TVLynn

Did you ever at least find the problem ????

camaro440

No not yet. Haven't had the time yet to pull it out. Been working on it to get the area prepped since I'll be doing it in the driveway. I'll keep y'all posted with pics and all. I'm thinking the sprang popped causing the drum sound

camaro440

I'll video tape the driveshaft when I'll accerate

PACT.com will have all you need

Consider rebulding it yourself ...they are not that hard.

camaro440

What company and kit would you recommend? I'm looking at a kit for the strip and street

TVLynn

Your best bet as listed is Pact. Just tell them your plans and they will get you the correct parts.
Or you can order a B&M kit through Summit

camaro440

The site that pulled up wasn't any kind of transmission stuff

Gorts 5th

It s there" PACT transmissions "
the kits they sell are just the ticket

Thanks. I like the camaros just not the motors lol. I have an extra block so just in case.

I just got off the phone with my father in law's brother who is a transmission mechanic and says that I bustef the low drum and the main culprit is caused by the the gears I have set up in the rear end. Says I should go with a 4.10 gear. I was thinking about going with a bigger bear than that for my setup

RacerHog

Go with the 4.30 Rear gear....
Ask Father-n-law to get the good stuff from CRT Trans.....
