precision industries converter

[OleBlackyLBZ]

I have about a 6-7 year old Suncoast 1056 in my truck, no billet stator. It has treated me right, well over 100,000 miles of hard driving, maybe 25-30 4x4 boosted launches on it(not many I know), trans tuning requires lock-up in 2nd but I've noticed anything over 550hp it does not lock every single time anymore, it didn't lock on tune #5 until 4th or 5th gear the other night on a Wot pull, but it only does that occasionally. Great converters especially for their time, they just can't compete with what's out there now. I plan to have the trans freshened up and send it back to Suncoast to be re-built into a 1078.

I haven't dealt with any SunCoast restalls, will they restall to a 1078? I'm currious because that is a Limitless exclusive that even SunCoast doesn't sell on their website.

I do find it odd you blew through the R as I've used it in trucks from stock to right around 900-1000hp in compounds and never once had that experience in ~20-25 converters out there in that stall.

I had videos showing how awful it was. 1/3 throttle and 1400rpm slip trying to merge into traffic. It was just terrible. Talk to Evan - he agreed and has seen it on many trucks like mine. He was going to get me into a 1078 but the 1077 went in and it isn’t coming out. The K was odd. Ok if all you want to do is hammer on the truck I guess, but I didn’t find it to do what it promised.

that one my friend is selling is new. 1700stall.
my engine is stock, upgraded head gasket, ported heads, arp head studs, light ported head, ported turbo, 3" ybridge, ported turbo horn, ish 400whp with sac 45now. are asking because i save 500 to 700 usd too buy this. are going to build trans. only road driven truck, some wot now and then. will there be best too buy a goerend ore simular? are looking for high torque transfer at low rpm. and not push thruu converter. want to keep rpm low att road. i'm pushing thru stock converter now, and engine rpm is a little too high before lockup.

Does he know what stator/pump assembly is in it? The negative pump style from Precision couples decently well compared to some of their other stuff.


If you've got the mods you say you do, a converter isn't going to save the possibly already compromised transmission. You should start thinking about saving for a built trans.

I talked to them maybe 4-6 months ago and they said they could.

Maybe your truck isn't putting out enough power to put that little R into coupling mode

Wally and i went back and forth on his issue when it was happening. it was strange for sure as ive not seen the R do what his was. Evan did say hes seem them do that though. maybe a bad run of them or something? no idea.

Just pokin the bear haha

 

[N2BRK]

Haha. Probably!

James - even George said he’s seen LMM trucks do odd things with a converter, he pulls the converter and sticks it in an lb7 and it acts fine. Who knows. I tried tuning, trans rebuild, new Tcm - nothing changed what was happening. Then I went into hyper search mode and actually read just a couple posts about others having similar issues, so I decided the 1077 is my best compromise and I’m happy enough. I’m sick AF about dealing with converters on my truck.

Probably yet another set of tables EFILive never "got around to mapping".

transmission is going too be build, was thinking if this converter i worth the money, or just grab a limitless or goerend in first place..

Do it once do it right. It's alot cheaper in the long run.

then i skip this one, would have saved me some money, but too risky...

I would pass. There are better converters that are more efficient and if you want to make more power than stock a converter won't do you any good. I had a PI white ML converter and switched to the 1078, what a difference in putting power to the ground.

I had to replace the "R" in my MikeL 6spd that was installed in 2019. It started locking/unlocking in tow-haul when pulling up a grade and trans temps towing were 200°+. The replacement "R" has been flawless ever since and trans temps are back down to 170°-185° when towing our 11k# TT...

7 trucks with Precision in my area have all failed under 15,000 mile and they will not do a damn thing to help ,BS must be made in chine ,what gose around comes around, just got a call from a frend his just shit after 8000 miles WOW no help

 

[TOMAN]

My Suncoast has over 700,000 on it , all is good

 

[TOMAN]

Have 9 Goerend in truck and all is good so far see below, replaced all the NonPrecision with

Goerend HD Billet Stator Triple Disc Allison Torque Converter 2001-2016 and all is good​

Holy sweet Jesus! Jeff Toman?!?!?!?!?

Almost a million miles on the old girl now?
