Since my trans is out at the trans shop i want to have a vette servo and shift kit installed. i emailed BB 4 days ago and they wont respond can i have the shift kit and servo installed if my tune had the shift pressure increased? I dont want to blow the trans or toast the clutches from shifting too hard

Yes you can. The 1-2 shift will hit harder than before, so it may be slightly unpleasant if your shifts are already very firm due to line pressure increases.

 

Your trans won't mind banging those shifts out. If anything is in pain when slamming through the gears, it's your u joints and differential, but I wouldn't worry about it. You're probably not shifting anywhere near hard enough to affect those guys much.

Ok so i will be fine adding a shift kit and vette servo to a stock 60e that already has the line pressure increased for firm shifts?

It will be fine.

 

 

Keep in mind the typical 4L60E seems to fail in the 140-180k mile range, or sooner with abuse (heavy towing, mud bogging, burnouts etc.) So I'm not saying it will last forever, but the addition of a 'Vette servo isn't going to be the cause of its demise.

The trans has 126K miles on it

The quicker it shifts the less heat it makes and the longer it should last. I would install an external trans cooler also. I had my 4l60e built by cpt transmissions and it was a beast.

I got the vette servo, bb tune line pressure turned up and oem cooler so it hits real hard. Barks em at wot. The kevlar bands i have also dramatically decrease temps

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By KARNUT · Posted

      Starting at 17 running parts for my father’s construction business to haul our equipment. Eventually doing shows, sales and training after purchase. I drove a minimum of 50K miles a year. Half hauling something. After retiring 30K miles a year to the last 2 years 15K miles a year. 2/3rds highway driving. The major contribution to fatigue for me is from anticipation and awareness. I just don’t relax. Too many idiots on the road. There’s two kinds. The group that never leave the left lane tied together afraid to let anyone in doing 80. They’re mostly on weekends. Then the left lane sleepers usually next to a tractor trailer not advancing. Eventually the tractor trailer will drift over the sleeper will wake up. The train moves and the tailgaters who are usually mad as hell. You definitely don’t want to mix with them. The tail wagging bumper puller’s with under powered trucks are holding the tractor trailer up. That bunch are dangerous. I usually pace ahead all that. Unless there’s a gap when I can chill and let the speeders pass. I tried all different types of driving. I stay to the right except to pass, it’s the law that’s getting in forced more now because of road rage. I was so happy when my wife didn’t want to do the camping life. I had enough of pulling for work. The family has a bus and fifth wheel. I haven’t driven either one since retiring. No thanks.

      Yesterday a suggested youtube video thumbnail caught my attention so I watched through it and it was a bunch of short clips someone gathered together of people pulling trailers, a lot of them were bumper pull holiday trailers and a pickup or suv pulling it. a few fifth wheels as well, some motorhome crashes also. The tail wagging the dog theme was quite evident in numerous self inflicted accidents that took out vehicles around them sometimes in the process as the unit finally swung around and flipped over in the middle of the highway. Or the other classic which literally could be called "I forgot the trailer was back there" in passing another vehicle on a multi lane one way freeway and then cutting back in line before the back of the rv trailer had passed the front of the passed vehicle and often in front of a tractor trailer and that never ended well. Or the wide kick out swing of the rear of a long travel trailer as they have so much overhang behind the axles and the trailer smashes into the side of vehicles in the next lane over ( typically sharp turns in city driving ). It makes one leery for good reason to be near an RV trailer after watching a video like that and be it on the highway, in town, or at a gas station where that rear end comes swinging around due to the fuel station being so cramped and not intended for larger trailers. I wonder how many officers have heard those words though "I forgot it was back there" as they investigate the accident LOL.

      Just because a person can buy a travel trailer or a motorhome doesn't mean they can drive it properly. My observation during my RVing years.
