Topic: don't know what i'm gonna do about this.

[ghost]

if i was ticked i would fight it. however they ticket the home owner(land lord) for stuff like that. i've got over 2k worth of slips on this for just this last year. i'm gonna talk to my dad probably tomorrow morning and see if i can put it over there for the winter.

I've read elsewhere on the net that the pump can be replaced without even dropping the tranny, through the pan.  Google it.  I did.

Is this the pump you need, brand-new for less than $130.00?

Better yet, if you tear the pump apart, you might be able to replace just the damaged parts (rotor, vanes, etc.) with parts from here:

http://www.bulkpart.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=2&Category_Code=4L60-700R4pump

I suggest you fix that POS and then either drive it or sell it ASAP.  You obviously don't use it since it has been sitting for 1.5 years - and it's not even driveable!

Don't even dream that you'll get anywhere near $10K for it.  Hot rodding is for pleasure, not profit.  Sounds like it was a fun project.

here's the skinny on this situation. my other ride is a 89 s10 blazer, pretty nice really, factory 2wd 2 door, lowered almost 3inches front and rear, with (best part here, you ready for this) an l98(sb corvette engine 355ci stock) and a turbo 700 trans under the hood. spent 2 years building this, and drove it for about 6 months. then the transmition went out(never buy one from the junk yard for a hot rod engine). anyway i get this call from my landlord tonight and he's pist, seems he got ticked for my blazer being parked here with expired tags. he have me till the fifth to fix it or move it, then he's gonna have it towed away. i don't have another trans to put in it, and i don't have anywhere i can move it too. i've invested close to 10k into this blazer over the last three years rebuilding everything from the engine and fuel injection to the one off suspention setup and the hand fabricated rear deflector. i'm not asking for a hand out(but if someone had a transmition lying around..)

[mark]

i have a turbo 350 that i've been thinking about swapping in. ....

Do it. The 700R4 was/is crap.

The trans has to come out to fix the pump anyway(as if it could just be the pump). If it's an '89 and it hasn't been rebuilt recently then it needs to be rebuilt.

The TH350 (excepting the late 350C) is a far more durable and reliable unit and can be completely gone through for about 1/3 the parts cost of the 700.

My 2¢.

Wish I could help.
Sounds like a sweet ride.

thanks for the rebuild link. i'm gonna fallow that advice, next spring. my blazer has only been sitting since march this year when i blew the trans out. i'm not 100% that's it is the pump but that's the popular beliefe of those who witnessed it. i talked to dad tonight and i'm gonna store it over at his place on my trailer for the winter. then next spring i'm gonna swap in the 350 and call it good. i never intended to sell this blazer from the day i bought it. this is just always how i've wanted it to be. this has actually been the best ride i've ever owned. i bought it back in 1991 and proceeded to drive the hell out of it till the original 4.3 finally gave out at near 500,000 miles that was in 2006 that's when the build began, complete frame up build, and i cheaped out on the last major part i had to buy. this is no pos. this is project ss. sorry if that sounded a little crazy, i'm a little stressed

[mark]

okay so it sounds like it was "driven into the ground" = rebuild time.

rebuild link had some good info. If you keep the 700 expect a $1200-1500 bill for the parts, including upgrades. Don't skip the upgrades. Buy new sprags and needle bearings. You won't find much in the way of hot-rod parts because the 700 is not a hot-rod trans. The Haynes book has better pix than the ATSG and doesn't assume that you've done this before.

If you haven't done this before the 700 is not the trans you want to learn on.

The pieces to build a race-ready TH350 ran about $500 last summer(shifts harder than I liked but the kid loves it). $350-400 for a stocker.

Good luck.

[mark]

oops... never mind.

I just caught the part where you have a V8 on a V6 trans.

That aint gonna work for very long anyway. The parts bill just went toward the high end, unless you have a buddy at the local shop that can fix you up with most of the innards from a V8 trans.

If it quit working in front of witnesses, you probably lost more than the pump.

Toss it out and use the TH350.

After reading this entire thread its got me thinking about the V8 S10 i have on the go as well...Does anyone know if the speedo cable interchanges between the different GM transmissions? That was one of my main concerns when it came to using a TH350 in my truck..well that and a lack of an OD but i was planning on buying a used TH700R4 from a V8 truck not an S truck.

[eldar]

What happened to the good ol 400 trans? Always worked good when I used them and had overdrive.

400's about the toughest auto trans. IMO. But what about a conversion to a Manual Transmission?

If you're looking for some advice on chevy repair (on top of Ed's handy links), my chevy nut brother hangs out on this forum quite alot: http://www.fullsizechevy.com/forums/

I do recall him talking about 700 problems in the past...

 Matt.

There was another tranny, a 4e60 I think. It was on the 4.3 litre engines and fit the 350 too I thought. But it might require computer control.

[DarkRider]

Ummm actually the TH400 was a 3 speed just like the TH350. That much i do recall from when i had my Sierra. Besides a TH400 would be overkill for my ap...but not for ghosts.

[eldar]

Really? I thought they made a 4 speed or should I say 3 speed with overdrive version. Maybe I am thinking of the 700 then?

i've wondered that myself. the speedo in mine is electronic, and while the connection fit from the original trans, the internal parts were not the same, at freeway speeds it would read like 5 mph.  oh and the 700 is the overdrive version of the400       

[DarkRider]

Actually i think the 700 is based off of the 350.

Yes. With a hatfull of possible drive gears to match axle/tire combos.

700R4 had hydraulic shift/computer lockup. 4L60E was the fully computerized version. 4L65E after 2001 is slightly beefier.

Correct, and correct, and probably not. The TH350 can handle whatever ghost's smallblock can dish out. The spider gears in the diff will break first. (hey, did you check that?? does the speedo still read while you're going nowhere?) I have a S-truck axle in the racer and have busted some with my itty-bitty 2.3L .

hmm.

dunno about that one. the insides are pretty different. The Ford AOD uses a lot of C-6 parts though.

 

[eldar]

Now your just tryin to show off!

[mark]

maybe so but I'd still look at the rear end if something went bang and it doesn't move anymore.

 

[ghost]

i'm sure it's not the rear end. that's um overkill for my little v8 (already delt with that problem when i built the suspention setup)it didn't really bang, it was more of a pop, then no more gears. i probably should post up all the mods i've done to this, but it might be easier to post what's stock

[edbikerii]

Dumb question, but have you put her in gear while idling (up against a brick wall or something) and looked at the driveshaft to make sure it isn't turning?  Probably be safest to have a buddy check for you while you hold the brake.

[ghost]

actually i have, checked it myself when it first went out. don't even gotta hold the break, almost like the shift cable is gone, checked the cable for opperation, even dropped the pan to be sure everything inside was still intact. everything looked good, but it don't engage in any gear, that's what led me to believe it's the pump, possibully the torque converter but that's got less than 5k miles on it. i'm gonna load it onto my trailer tonight and haul it over for storage early tomorrow morning. i'll just deal with it when tax time comes, that's only a couple months away anyway

[mark]

fwiw, I'd still go with the 350.

the 700 is fussy and complicated and needs expensive upgrades.

the 350 is simple and rugged and if cash is an issue you can build one on the kitchen table in a few hours with a gasket set and the best bits from a couple of scrapyard cores. Frictions can be reused if the material isn't burnt or crumbly. Rebuilt torque converters run around $75 for a stocker or $150 for HD/HP type. Besides the coupling function, the converter acts like a centrifugal oil filter and holds all the wear gunk from the old trans - kind of a change it or else thing.

A can or two of Cooler-Flush(removes debris from there) is also a good thing - so is an inline filter in the return line.

[ghost]

yea i've got a built th350 that i was saving for my in law's latest coupe project, but i'm gonna put that one in the blazer. let him find his own. i'll need to fab a cross member for the trans, and either have the drive shaft lenghened or move the engine back like another inch or so. i think that'll be easier anyway than dealing with another 700. anyway it'll still have to wait till spring. all my shop space is taken up between my rides and the in laws rides. i'll drive the neon another winter(assumeing it ever snows this year. i'm still riding the bike most days) and fix all those pesky oil leaks we all get on my 650 over this winter, then tear into the blazer early spring. i think that's my plan

[DarkRider]

I was just reading an article in sport truck mag about V8 swapping in S trucks. You shouldnt need to alter the shaft at all if its a stock part. The V8/TH350 combo is maybe an inch shorter then the V6/TH700R4 combo that was once in the truck...unless of course you had the shaft shortened when you put the V8 in. If so why not just go grab a stock shaft from the Junkyard and swap in the TH350. Problems solved.

[mark]

sounds like a good plan.
