Around 1975 ish…. Not the cleanest ‘68 Camaro, but had a 427 and turbo 350 with a kit. Had a perfect interior, the body was solid, and I loved it.
I was painting boats back then, and aside from rent most of my money went into this car. As usual 😎

 

@vette4fl Nice ride Bill. Thos were some mean *** cars then (and now too). My first mod on her was adding a 671 on the 454 (not stock lol) and she pulled many a 10 second ride. n LA I ran around with Bill ***** and the LA Street Racers. Those were some fun times and this was before he got permission to open a strip in the Harbor area. Before the Harbor strip we would meet up in a Buena Park shopping center to pair up the street races and then go to the race place. This was behind the old Nabisco Factory in Buena Park. There was this 1 mile stretch of road behind Nabisco that was used primarily for shipping and receiving for Nabisco. There were RR spurs also toward the end of the half mile mark. The local LEO's would block off the road from the main entrance to Artesia Blvd so that regular folks would not enter by mistake and get hit by high speeding vehicles. Of course, truckers had priority, but we usually ran between 1am and daylight which was the low point of operations for truckers. The LEO's were volunteers off duty and some of them raced against us too!! What a blast because everybody wanted to race a cop car and get bragging right if you won. Good times for sure This is her when I was stationed at Lowry AFB in Colorado. My buddy's car next to mine was a 442 but I cannot remember for sure it's been so long ago, and memories tend to fade.

 

nice wheels on it. cragar?

grinder, thats very interessting, having it shift at 7000 and for that long. are we talking about 600hp to the wheels and wot shifts? stock trans internally? thats not much less torque than what mine sees.

on the "truck forums" there is a clear opinion: dont shift a 4l60e above 5500, it will die. when i started to logg line pressure i set the shift points back from 6500 to 6000 again, because i saw a decrease in line from 325psi to as low as 250 after 5500rpm. its not consistent, making me believe something is giving up, i reckon the pump starts to act up, even with the double "priming" springs we have. i need the trans to keep working for a while, because of other projects i dont have time to mess with this car.

who else is shifting a stock 4l60e that high?

 

Speaking of cops racing…. Remember when Dodge police cars had 440’s ? Fun time.

 

Yes but the 440 6 pak was the ***** out thumper. I think they were called Police Interceptors. I remember a few friends back in the day bought a pair from the junk yard and the police auctions. What a wild car that was man.

 

an amendment maybe:

if you get a transmission oil of "reputable origin" that mentions dex3 H in the specs, its fine for regular use. its even possible you get better mileage (difference probably not measurable). the contemporary formulation makes up for the lower viscosity, thats the whole idea behind dex6.

for a high perf application, where the oil sees high temp and loads, however, you migh want to think twice, and choose an oil with the original dex3 viscosity or even a bit higher (→"high temp atf").

today its difficult to go by the specs anyway, as they are mostly economy oriented (for engine oils as well). e.g. the good, old tes-295/389 spec for extreme duty oil: any decent product will surpass it today, whether they put it on the label or not. this might even hold for tes-660. for high perf its best to ask the manufacturer or go with a "boutique" product in the first place.

 

What do you mean Lenny? The link you quoted specifically says don't use dex vi.
"ATF Type III (H) GM auto transmissions from 2005-and-earlier model-year vehicles that are no longer under warranty, where the OEM previously specified DEXRON III H, DEXRON II or DEXRON ATF."

 

For what it is worth, I have been using Red Line D4 full synthetic ATF for over 11 years, five fluid and filter changes, 40,000 miles, 25 road course track days, 8,000 full throttle upshifts 2nd to 3rd in my 2001 A4 C5.

Routine transmission temperature reached 250 on track until last year when I installed a giant transmission cooler.

Full synthetic ATF is much more resistant to oxidation at high temperatures and thus is much less likely burn and deposit transmission killer residue.

 

A couple posts ago you mis-quoted "ACDELCO", now you're claiming gm and Tremec have a different answer.
If you have evidence to back up your claim please share it. An assertion without supporting evidence should be dismissed without evidence.

 

Happy Thanksgiving To All and especially to my Veteran Brothers and Sisters and most especially to those who didn't make it back whether it be physical or mental.

 

The only evidence you provided is from 2011 and may have been the correct information at the time. Posts 5 and 8 from this thread both say Dex VI isn't the best choice (although the gmserviceinsights article is undated). The Mobil 1 tool is current and verified by a Mobil 1 Lubricants Technical Support engineer R. Caballero via email on 21 November 2023. Their tool suggests Synthetic ATF or ATF D/M. Mobil makes a Dex VI but does not recommend it for C5 transmissions.

If you're an Amsoil fan, they also have different lubricants for Dex VI and Dex III.

 

Litttle late on this but yes sir, Cragar originals with the Blue caps. Later ones came out with red caps. Cheers!!!
