Default Pete K Transmission help?

Hey, I had my tranny built 10k mile ago, and today I no longer have third or fourth.
I had it rebuilt useing the following.
Trans Go Shift Kit
Kevlar Bands
Torrington Bearings( this is on the invoice)
Etc etc were just stuff to rebuild.
I also had a Vigilante converter.
Well today 3rd/4th gear went bye bye.
I am sorta still under warranty here in Oahu, and will take it back.
What do you think is broke?
And how would you recommend I rebuild it?
Its a 1993 700R.
Its not making any noises, just a whirring noise like a pump?
It has a external cooler, and a BeCool radiator transmission cooler within the radiator and I used Mobil 1 synthetic. My Ratek Laser temp gun never showed above 160 degrees on ther lines and pan.

The whirling noise is not typical. Likely in the pump though. Anytime a fresh trans wipes out 3/4 it normally can be traced back to tv system or governor. Those 2 seem to be the common causes for the 3/4 failures .I would suggest having the pressures checked immediately after the refresh.
This will allow them to tweak the tv adjustment before it leaves their shop.

I assume that they installed the tan clutch plates. The alto reds are triple the cost, but you may want to install them. Based on your et, you are making enough power to justify the expense.A high rpm Sonnax pump slide spring is a good thing to have also for an lt1 car. If you have installed an aftermarket 13 vane pump, I would suggest swapping back the stock gm 10 vane guts.
And last: * Have them leak test the servo check ball capsule*
4 out of 5 times they are fine. Most techs forget to check them. If this leaks, and they rebuild without changing it, it will fry again.

Inspect the 3-4 accumulator housing in the case. If scarred, they make a $50 sleeve kit that fixes it.

Thanks Pete. I will be talking to the shoop today. Hopefully since he is in my Corvette club, we can sit down and figure out something. I will print the recommendations out. I have a feeling its the TV cable caused this. The shop did a C3 conversion to a 700r and ahad this happen before.

You can. It should be approx 60psi at idle and approx 140-160 psi wot. Check the book for the specifics. Your numbers will likely be a bit higher because transgo uses a higher pressure spring.

Thanks Pete. I saw your transmission for sale in the other section. It cost 1700 bucks out here, and thats with a discount. Yours with shipping to Hawaii would have been cheaper. Crazy huh!

Shipping has been deadly lately. Prices climb almost daily. The trans I have for sale is not a "worked" trans. Just a good, solid, reman with a few upgrades. I just did a "worked to the b*lls" trans for 85 stalker. His had all the bells and whistles. It was much more expensive, but serious hardcore parts for a 700 are stupid expensive. I ran a similar trans (in my own 87)to the one in the 4 sale section for 7 years. Smoked the 3-4 pack eventually. Ran dozens of bottles of spray through it and hundreds and hundreds of 1/4 mile passes. It should not have held up so well. Lucky I guess.

Pete - May I suggest a shipping alternative for you... direct air freight. I know that Nanticoke isn't all that close, but Harrisburg has a big enough airport that it might be worth checking into.

Toss that sucker on a non-stop (or non-change) to Hawai'i, and watch the costs drop.

I am not kidding. Those cargo holds are huge and the airlines just love the income!

Same thing applies for anyone living near a major airport.

I have considered it for some odd sized packages in the past, but it never worked out because the sender or recipient lived to far away.

However, for something like this, it might be cheap enough to consider. Same thing applies for just about anything being sent to Oahu, too... jeez, nothing is all that far away on that isle!!!

If nothing else, it's worth looking into...

I appreciate the tip. I have a smaller airport locally. About 20 miles away is the Scranton, Wilkes-Barre international airport. I will check into it. I mentioned to Mrs. Kane that I might buy a plane ticket for myself and the seat next to me for the trans. I would not mind a trip to hawaii

Tell you a funny story: on another car's forum, this guy in Jamaica I think it was "hired" his friend from Indiana to bring down parts, his wife, and stay at his place and repair his car. It was about a five day vacation and work and the car got all fixed with parts that would've been ridiculously priced if he'd tried to import them.

So, maybe there's a Hawaii in your future?

[damm, i just passed through Scranton area this past weekend; even went to the Lackawanna RR station, etc. just for fun)

Steve, who built it? I've still got some friends over there in the Paradise Cruisers car club who can probably point you in the right direction if nothing else works out. We had a buddy there running 11's on one in a Yellow 70 El Camino that held up pretty good. Shame about the track closing.

I hope they have they have the factory book for the car.
I think you have the 4L60 trans .If the tv cable is off just an 1/8
it will go away again.
These are adjusted different.I have someone floor the pedal and pop the black flip thing and slide the black part of the cable to make sure the throttle is at wot,at the throttle body.
My 2-3 shift still sucks but the trans guy said he did not know how to build a 4l60e.1-2 shifts great but 3-4 sucks.
I have a monster trans I got screwed on and it still doesn't shift.
Now it wines like crazy when I let off the gas.
The guy at monster says it worked fine here
Doesn't it always.
I have no tv cable and nothing to adjust and he says it is an adjustment
Stupid is as Stupid does.
I may fly Pete K over here to fix it.It cost me $829.00 to ship it to Florida and they shiped it back to only $350.00 and 95.00 for the GM sprag they told me after Pete K ask ed if it was an aftermarket 5 pinion sprag or GM.They say the trans did not wine when they tested it .Ho sure the check is in the mail and I won't in your mouth.
Never buy a trans from MOnster it will be a nightmirror.

I had a rather large shop do it here. He was a fellow corvette owner, now an F430 owner. But he talked about all the right things, and he is going to do it again, and I pay for parts only. He recommended the torque converter be rebuilt, to keep any foreign parts out of the new rebuild. I feel it was the TV cable or something out of whack?
Most places were around 2500 bucks, before Converter and any hard parts needed.
Still, Pete could make a profit, without a doubt as with shipping stuff is still cheaper than here. The warranty would be the only factor, if given one.
But a flight to Hawaii and a few tranny rebuilds and your vacation is paid for

Steve, having just gone through my 4L60 (1993) there are a few things i'd like to remind you of and I'm sure pete will chime in with as well..

1993's are a one year only tranmission.. they do not interchange with other 700's or 4L60's.. The valve body has an extra check ball, an extra pressure switch and a few other nuances...

For my rebuild I went with

-Full Aalto Red Eagle Clutches master rebuild kit w/ kolene steels
-.500 boost valve
-new GM plaanitery gears (4 pinion) - make sure you get teh real dea GM.. I've been told this is better than a knock off reman 5 pinion.. GM 5 pinion i suppose would be better but more $$$$
-generic space/seperator plate - the correct plate is discontinued from GM (1993 specific) I ordered a few shift kits hoping the plate they had would work.. non did.. The generic plate had to have a few holes added to it.. but otherwise it worked good.

PeteK was VERY helpful through my 4 week rebuild ordeal..and is a wealth of information!! good luck - your in good hands!

Well Thanks, They should have the tranny taken apart soon, today/tommorow, and I will go down and ask some questions and maybe take pics? I noticed the 93's were/are specific in more areas than one. Look at suspension etc. Crazy.
For the seperater plate, since the tranny worked for 8kmiles, do you think TransGo had it right?

Its hard to say without placing one plate over the other.. All I know is of the three different plates we looked at none had it right.. we had to modify a generic plate (which was the closest of all of them - only need to drill a few small holes using the original as a template). From my experiance the easiest way to tell if they have it right is if the shift kit (seperator plate) part number for the 1993 corvette 4L60 is different from the 700R4 kits that go from 1984-1992 and the 4L60e kit that work for subsequent transmissions.. in my option its such a nitch transmission that it isnt worth anyones time to make one.. If you do find one that is exact start a new thread and post the info (so it comes up on the search for other people in our situations).

BTW: I like the '93.. orange dash, seperator to keep the passangers away from the radio.. and we still have a glove box! the best of all worlds!
