So you just replaced the factory turbo w another? Are those the RV 275's?

Well I finally have another Alt in my truck, I got it in my truck this afternoon & had to go to a Cleveland Indians game tonight, my wife won the tickets, great seats, perfect weather. They did win against the Detroit Tigers, Yipee! But thank you all! It was worth my time combing through the TC issues here. I don't think I would have started w the Alt again since I don't have that many miles on this rebuilt one. Then alsoThanks to someones suggestion of having the replacement checked before I left the store. Three out of the four replacements were bad on the VAC side, including one new one. I would have been chasing me tail for weeks. Even the guys at the part store didn't believe it. I didn't even start it yet but it should be OK. Now, what makes the diodes go bad, this is like my 4th Alt & I only have like 203K. I don't mind cause the replacement is lifetime & I can swap out the Alt now in about 20min. (less time than I can clean a horse stall) Whinee!!!! Thanks again, Dave

I had no idea of the sensors that are on this truck esp a battery one. What are the new trucks like?

Good question on the exteral diode plate!

Looks like you have some extra fine juice in your truck, 12V! I like those torque numbers, nice 833, I Like it! Is 1996 the first year of the 47RE?

I too run w the trans temp gauge, using it the same as you Jag1. Is it stated anywhere that we should not tow in OD? I thought that the Overdrive was designed to allow the engine to run more efficiently! I do not have a pyro or a boost gauge but I usually drive to get my most MPG while not getting run over by the 18 wheelers if that makes any sense. ST tires are only rated for 65MPH so I try not to push it much beyond that. Wow a 28' fiver, don't give my wife any ideas! For me I'm only a standard cab, so that would be like the tail waggin the dog. She has in mind a resto on one of the old Spartans. I hope not, this 16' Comanche is plent big for the two of us. What mods do you have to pull a camper that big? Are you following Michaels recipe? So this afternoons activities included pulling the Alt getting it bench tested at Advance Auto & it failed the diode test, it said 8.1. So I had the guy check the replacement they were giving me & it failed too. So I have another coming in the morning. So since I needed to get Hay, I had no choice but to but it back on, it did run better the Hunt happened twice & after that ran like a charm at Highway speed & enery speed in between. We'll see what happens in the morning, w my luck they did the set up for the test wrong & I won't get my replacement or something like that. I'll keep you posted, Dave

My situation is a little different, the guy that pulled the Trans & the guy that worked on it are in two different locations. The rebuild guy, in his mid 70's, very old school, only rebuilds, I don't think he has any diagnostic equipment. While he was rebuilding it he had me go over & check it out, the only thing that was worn was the 4th & OD because of the 4th gear hunt. I did take my truck 2 years ago to a Dodge service center& he reflashed my PCM or ECM don't remember, you guys know what it would be. That mechanic told me that my TC was weak I needed it replaced. So since I was getting my TC replaced I figured I should have my trans gone thru, esp since that is the weak link on the truck supposedly! I just called the guy that removed & installed the trans, he said just to pull the Alt take it back to Advanced & get another. So one more question, does Chrysler recommend not to tow in OD w these transmissions? The saga continues, Dave

I have the original battery cables in perfect condition. I wouldn't know how to remove the 4th gear hunt fix. I took the downloaded copy that was sent to me from this site years ago to a trusted mechanic, I hate wiring issus, he's no longer in the area. That fix just added a ground & bypassed some wires but...........?

Thanks Michael! Been locating & cleaning up my grounds & Alt conections. Not sure my tester is good enough, ACV has 200 & 750, not sure it will pick up a 0.1 or smaller. It's an Actron CP7672 model, bought it from Advance Auto, Dave

I hear ya MnTom & Joe Cool. When My trans was rebuilt, the only thing bad in it was 4th & OD from this Hunt Haunting. I'm going to try grounds that I can find, check the quick connections from the 4th gear hunt fix, that Michael sent me years ago. Also in nother post Michael thinks that this is all caused from a bad diode. It could still be diagnosed w the Alt is still in the vehicle? Thanks, Dave

So what grounds need to be cleaned do you think? I had mine cleaned on the batteries when I was using a Battery Tender over the Winter. Mine never left the Garage since November. Thanks, Dave!

So I Check this at the battery or the Alt?

OK, Here's what's happening, John the transmission guy is saying since I towed my trailer in OD he's saying I burned up the trans. I don't think so, fluid is still red, no burnt smell. He's saying that these automatic transmissions were never intended or capable of towing in OD, only the 400LE's were made for that. So I'm not going to get anywhere w him help wise. He did say that since my check engine lights are not on that none of my new trans sensors are to blame. (this was in a phone conversation) I'm thinking that since we were on the ocean the salt air may have caused a grounding issue. Anyone clean all the grounds? I have no clue as to where or how many. I will have the Alt tested at Advanced Auto, that's where I bought a reman a year or two ago maybe w only 5-10K miles on it now.Thanks for posting that Mopar. In my last Alt I rebuilt it myself w a kit from Geno's Garage but one of the diodes went out. My camper is like a 16' 2280 pounds empty, 1968 Vintage Comanche single axle, it's like a flea is on my hitch. I had no heating issues needle never went off the peg while driving. It did go up to the yellow zone, 180-190, sitting in traffic waiting for an accident to be cleared in NC but as soon as we moved it was cool again. That was on the way to Georgia. Mopar, years ago sent me a schematic w directions from here for the 4th gear hunt fix. One of the lines was not supposed to be cut so he used a quick connect. I will take that apart & solder the connection. A friend of my has a 96 w a 12V he had the same problem (4th gear hunt) but backed into a loading dock, jarred the vehicle & never had a problem since. So if anyone can help me on the grounds that would be a start here I totally guess! Dave

That was my Wifes suggestion as well. I don't know if a sensor is going out or what. I will a least give them a call now. This guy is a master. Will do, will let you know what I find out. Pontoon Boat season is getting closer too! Thanks, Dave

Hi all, it's been awhile, I had my trans rebuilt about a year ago w an RV converter upgrade. It has been great. So last week I pulled my 68 Comanche 16' camper trailer about 800 miles from my home to Tybee Island, Georgia for a Vintage Camper Rally. Not even a hiccup! I just drove the truck a few times w no camper while down there & it was fine. On the way back, it would hunt & then go back to normal until about 1/2 way home than it seemed like it would slip in any gear. I watched as my trans temp gauge started to climb as did my engine temp, so we decided to stop at a truck stop for about 10 minutes. After that it was fine until we hit the hills of West Virginia, the truck seemed haunted. When I took my foot off the throttle it would seem to like engine brake & I don't have one. Again same thing w the gauges. So we stopped again, this time for 1/2 hr. Seemed fine again, may have hunted two times but was perfect the rest of the way home. Any ideas, do I need a trans lock up kit? Dave

I've had really good luck w Battery Tender chargers. Just move them around once in awhile. I'll try the engine oil trick on the connections, something else to do w the used oil.

Well had to sell her about a month ago on eBay. Just didn't have the time to keep her on the road. Think I was just to picky, instead of fixing what was wrong to get it back on the road I started tearing further into it. But I do like my gaser BMW325xi. The guy I sold it to has a 240D & he made the conversion kit to run it on grease, sorta wis I coild have done that too! Dave

By the time I get back From Canada next week I will be real close to 200K.

I was thinking of using Thoroughbred for a re-man when the time comes. Did anyone ever get a list together of who rebuilds there own VP44? Don't wanna do this!:spend::spend:Dave

I'm really enjoying the upgraded Borgeson, like they say, steering you forward!Now if I can only keep the wife from buggering up the Cub Cadet riding mower!:sick:Dave

So I took it on an 850 mile round trip a few weeks back & my overdrive hunt has stopped. This is the best the truck has ever run for me, knock wood! I didn't do anything, ran out of time & had to just drive it. The only thing different is a few tanks of commercial B20.Hope I didn't jinx myself here, pulling me 24' pontoon up to Canada in a few days, another 1000 mi trip. Getting closer to 200K.Dave:hyper:

So the RV275's are the next step up from stock?

Thanks for sharing your experience!

Cool, it will be good to know! - - - Updated - - - Keep me in mind!

Yep think so Dave, Put about 400 miles on her today & she's working fine. Found some B20 along the way & she's purrin like a kitten. Turned over 198K, what else can I say? It's a good day! Dave - - - Updated - - - Agreed!
