Circle D Converter First Impression
 

I installed the 278mm, 3-3200 in my 4L60E. Trans has the HD2 kit and Oregon Perf. billet servos in it along with TruCool 40k cooler. I haven't run it hard yet as it's still in the break-in period.

Hard to believe how far converter technology has come! Quite impressive I might say! Kudos to Chris at CD who made the recommendation. You nailed it!

Truck is a 2000 Silverado ECSB 5.3 4x4 currently running the stock tune with 4.56's and 34" tires. I'm going to do some data logging and adjust the LFT's for efficiency before I reinstall my Predator performance tune.

Other than WOW!!! I feel like putting a line lock on this thing would be cool, LMAO!!

Has made my truck everything it should have been from the factory.

Satisfied Customer....:burnout:

break in procedure? WTF is that? how can you be satisfied before standing on top of it? tripple check the fluids and let er rip.

:jest:
If the fluid is up to temp and the level is right.. its WOT time!!
First thing i did was a 0-100 pull and a burnout.. :dewey:

LMAO!! My thinking exactly!! But I swear for the life of me, I can't locat the pamphlet that came wiht the converter right now, but I swear I remember reading in "the library" that CD recommended 150 mile break in period?? I thought it had something to do with the lockup clutch linings/surfaces mating...maybe I'm confused. Tell me I'm wrong.

I hope its not locking up at WOT anyway..

but then again.. stock 4L60E tune has the converter locking up in 3rd WOT ..

why get the tripple disk if you dont plan on locking in 3rd? the lock up on a circle d tripple disk feels like another gear. it locks quick and firm. feels awesome.

I had same converter, loved it! I installed it and drove around the block twice, checked fluid and left some nice black lines down the street with maybe 4 miles on it. Before the tune though it was locking up at wot in 3rd which made the truck(stock motor at time) a dog, get it tuned ASAP!

If it's not tuned for the 'verter, don't be surprised if it throws a shift solenoid DTC and defaults to 3rd gear only when you do try a WOT launch. Also, if you stand on it while it's defaulted to 3rd gear, you might smoke your trans.

Just a heads up. :)

Installed my fresh rebuilt tranny last Friday with circle d 3200, hd2, servos etc.. Checked the fluid and put a new tune on the truck. Several wot runs, 4 hi launches adjusting shift points, timing, and fuel.. Took it to the drag strip the same night for test and tune and cut 2.12, 2.18, 2.16 60 ft times in my heavy crew cab! Hasn't missed a beat! Another very very satisfied customer here also!

Thanks! Appreciate the heads-up.

Sweet and nice looking ride btw... Who did the tune or what tuner are you using? And how do you like the cam that's spec'd in your signature? Looks alot like the one I'm looking at.

A buddy of mine did the tuning. He uses hp tuners. 10 years experience in tuning. I haven't bought a camshaft yet. I had stock48 spec that cam for a tvs1900. But I recently purchased a set of tsp 2.5 heads with 1518 springs (10,xxxmiles) for $400. My buddy put his truck back to stock. I'm thinking of having them milled .030 and going with a tsp 220 on a 112. Still undecided for now!

I didnt break mine in, got fluid level right and then went and beat on it
love it but wish I had more stall

Wow! Great deal on the heads. Probably gonna freshen mine up w/5 angle valve job and maybe larger valves. My stock heads are supposed to flow reasonably well to .600 for a moderate street use. I'll probably clean'em up, put the new springs on them, drop the new lifters in put them back on and call it done. I'm looking at the TP/TSP 220 on 112 but have some reservations. MD smogs us here every 2 years. There's a few tricks you can use to get buy. I'm also looking at a couple profile's a couple forum members had custom ground to specifically pass smog that put down some pretty impressive numbers. Right now making parts lists and placing orders. Got the new water pump today and the Comp. LS roller rocker bearing upgrade kit. It'll come together. Just trying to get it right the first time without tending to over do it.. lol

Your comment about wishing you had more stall is probably the most common one. I may get to beat mine this weekend if the rain quits. Compared to stock is an appreciable difference. Too bad nobody makes a trans brake for a 60E, lol! Might help sensationalize the holeshot a little:burn:

Break in is only for the lock up clutches.

Chris nailed the converter in my former Camaro. Told him I wanted the best of both worlds (n/a & bottle). Circle D 4C 3800 flashed 3750 n/a and 4200 on the bottle. 60' improved .12 n/a and .10 on the bottle and gained 2-3 mph on the big end vs Vigilante 2800. I was still dialing in the suspension shooting for a 1.3x when the track closed. My best 60' was a 1.42 with 3600# raceweight on a stock 10 bolt. I'm sure it helped that I knew the weight and power that I was making n/a and on the bottle.

I will be a return customer with my next project.

I would love to have a brake in my truck, ran one in my brothers 92 rclb with a ATI TH400. Nothing like coming off the brake with a 4000 stall and over 600 N/A hp:burnout:

Well matted the gas pedal tonight. Wow. And I'm running the stock tune corrected for speedo compensation only. Tanked up with high test 93 tune goes back in tomorrow. Between the new FP regulator and the converter alone it's a runner. Can't wait to data log, adjust the LTFT's and PE and reload it. Can't imagine how much better a truck like this can be with a custom tune, larger valve heads, some more compression, TP 220 and headers. Unfortunately for my bank account I'll probably get to find out.

i started at 2800 stall, then 3,000, 3200, 3600, 4300, now i have a 4,600 sitting in the garage that i'm thiking about sending in to have loosened up. the 4l60e that i'm having built now will have a trans brake in it.

i have 5c from circle d there is no break in period thats a yank converter thing lol. i called chris and asked him he said make sure ur oil level is good and take it to the strip and run it.

Sweet! Curiously, who offers the TB valve body?

Dun! Thanks for the feedback!

Correct, no break in on a CDS converter.

And thanks for all the review and kudos guys, we love them!!!!!!

Chris

really think I am gonna call you soon for a 3600 stall chris

installing my 3200 this wednesday,cant friggen wait

rossler trans makes the 60e trans brake.
