Hemi fred..... Im not knockin the pg!! My good friend runs a low 7 door slammer, of the other race . He just spent 7500 bucks on an ati glide rated for 2500 hp. He runs a 622 reher morrison raptor motor 1300+hp. He 's got a deep pan and an electric cooling pump and can cant make them live. Im not going to make that kinda power i just want toughness and reliabillity. i live in bc canada, the temps are chill in our short race season. If a glide with a cooler and electric pump cant help a glide live what does a guy do? Thats why i want an over built bruno..... Maybe? Im still looking for options but i think the glide is out unless there's a better bang for my buck.

Toby,

You are like me. Over build and then no worries. I also wanted to run a Liberty. That is why I am. I would be running a clutch but the time between rounds if I run brackets is not enough but I have been told I could get a couple passes out of one adjustment.

As for having to tune the clutch, a good clutch tuner can get it on one pass. Seen it done and not on the pro level. We ran a clutch for a long time. trust me, once we hit the set up no one could touch us. But we also ran more power and less tire than everyone one else so tuning the clutch was a little tricky.

I will remember if it spins it is put together right...

Can someone give me a quick education? I always that the Jeffco was an update of the old Jerico's, but looking at the picture above, the shifters indicate to me that its more of a planetary style tranny, similar to a Lenco, although the picture makes it look larger than a CS-2 at least. Guess I've been in the Lenco dark ages too long...lol. Anybody have a web-site or info about them? Thanks.

Thanks for the comeback Cuda. So from what you said, I take it the Jeffco was built to take Lenco internals, correct? Have you had any problems with the reverser on the Jeffco. That's been just about my only real complaint with the Lenco, when they started modifying the original reversers to have a neutral for the Lencodrive or other converter style (Bruno's,Donovans,B&J's)the neutral gate is extremely narrow and really a pain sometimes to get in and out of forward/reverse after burnout using transbrake at higher (1600-1800)idle. The sun gear that engages the reverse slider could be a lot beefier in my opinion, although in my case being a used tranny to start with, it could have been abused before I got it and I just finished it off. Knock on wood, I havn't had any real problems with the new one since fall of '09. I do know most of the monster truck guys have gone to the B&J because they kept tearing up Lenco reversers. The B&J looks physically about the same size as the Jeffco in your pic, just wondering what the Jeffco's are rated at power-wise.

The jeffco is like a cs1, can take about 3000HP
Never had a problem with the reverser or engagement but my car idles at 1000 rpm. I heard of people having trouble at higher rpm's but that was with a clutch not a bruno. when the jeffco doesn't engage at first, I just hit the trans brake again to stop it in a different spot then it slides right in.

I know this is an old post but I have a new question... Those of you that run a Bruno, are you having leak issues. I have been running a Bruno/Lenco for 4 years without any major issues. The only real issue I have it has been a weeper/leaker since day one. I have found little things here and there (fitting or fluid return protruding into the oil pan flange keeping the pan from sitting flat, Dip stick tube to case sea, (no solution at this point) but I continuously find oil drops on the fins of the pan with no clear path visible, gaskets have been changes, different sealers to no avail. Anyone have similar issues. I recently didnt qualify of an event due to a...as in one drop of transmission fluid found after my burn out. I don't want it to happen again. Thoughts?

Yup, my Lenco leaks if it has oil in it. Tryd everything. My buddy said put a vent on it. I haven't done it yet, got to reseal it before I do. I get some leakage between the Bruno and Lenco but feel most comes from the Lenco. I sealed mine good, but after a weekend it leaked again. That's when my buddy told me about a vent.

This post is great, to see HemiFreds post was a good reminder.

My Lenco stays pretty dry but The Bruno not so much (Red Line lgt wgt ATF in Bruno Shell Rotela 30 wgt in Lenco). To document the issues an potential cures I did notice when I was filling it (Bruno) while the engine was running it kept burping out the fill tube. I pulled the vent tube off the connector (push connect fittings/tube) and it stopped. So my 1/4" vent line is not enough so I have some 3/8" push connect tube on its way. This may alive some of the leaking issues.
Another point for future reference is the converter pressure. I've been searching since I bought it for the "Best " pressure Looks like the consensus is 150 PSI, I've been running as low as 75psi and now 120psi, I'm bumping it up to 150psi next outing and will report back on what happens.
