More tranny questions (Tom L.)

Q: a friend of mine told me that you can expect lower fuel economy and youll see more smoke out the tail pipe when you travel in higher elevations. personally i havent experience this yet. however next summer i plan to travel into the mountains and that is why he told me what i can expect in terms of fuel economy and the smoke issue. i have a 1999 3500 ctd. everything is great until i am towing in higher altitudes. then it uses way too much fuel. is there an altitude adjustment .

the point is that you cant bitch about the tranny they put behind a 325 hp/610 torque engine if you beef the motor up to 450 hp/750 torque. it is ridiculous to blame that on dc. bingo. i have an 03auto with the 305/555 engine. it is a pulling machine and i really dont need to bomb the engine to tow with it. the tranny has been strong and i tow around 11 to 12 k regularly. i have one of the first isbs 215/420 and i havent had a problem pulling anything yet. -- max give a man a match and he is warm for a short while. light him on fire and he is warm for the rest of his life. on sat 22 oct 2005 170403 gmt max dodge max340@verizon.net wrote if you bomb it you need to have a manual tranny or upgrade the auto. even with the manual trans the clutch can slip. good point. several people on tdr have upgraded the clutch when they bombed. the point is that you cant bitch about the tranny they put behind a 325 hp/610 torque engine if you beef the motor up to 450 hp/750 torque. it is ridiculous to blame that on dc. i have an 03auto with the 305/555 engine. it is a pulling machine and i really dont need to bomb the engine to tow with it. the tranny has been strong and i tow around 11 to 12 k regularly. .

says... i had a local speed shop install an electric starter in my 04 1500 hemi qc. the make was dei. a real piece of crap . very little range. i was thinking about ripping it out and having the mopar unit installed. anybody know whether or not the mopar might simply be a plug in type unit that i could do or does it half to be done by a dealer i have the remote door locks already. i par my truck about 200ft from my apartment and it doesnt start. ive had 3 trucks with dei remote starters. there have been zero problems related to wiring or installation my present truck seems to cook the brain of the remote starter about every 9 months its a 15 minute job to put another one in and its totally under the lifetime warranty. all that happens is the blower wont run when its in remote start a hassle in the winter for sure its something that my truck and only my truck seems to do. they even checked it out for too high or low voltages and spikes etc and it was cleaner than usual. the last one they put in is a year old now so maybe its cured. range is almost ridiculous. just to see how far it went i parked my truck in the upper left hand corner of a very large mall parking lot and a friend took me to the lower right hand side and it started with no problems. i couldnt see the truck the mall was in between. he took me down the street another big block and it still started. this was at least a quarter mile! more than enough for me. if i have to walk 10 minutes to get to my truck im parking in the wrong place. i think you may have a dud or the installation was messed up. the place i had mine done all three times has been doing them for over 30 years and the guy who put the last two in had been doing them nearly 10 himself. when they dont need to open up the installation instruction sheets anymore they have done enough of them to have it down. btw i would be shocked if the mopar starter wasnt dei. they make most of them the decent ones anyway. viper clifford dei all the same company. why the car companies waited all this time to put them in is something i just dont understand. now if they would just give up on the crappy head units they put in most cars. just make a deal with pioneer or someone and use a standard mount and when you buy the car/truck you can pick any one of say three or four standard sized head units and three levels of speakers you want from them or no stereo at all with just the hole in the dash and the wiring already set to go.. bdk .

dead stop when i was about 1/2 way home. when i got home i put the thing in park and just let it idle for a bit. the tranny temp gauge was up about 100 degrees more then normal; where normally it will cool right down when idling. i left the boat out on the yard so i could wash it the next day. the engine temp was in the low end of the normal range and the exhaust temp had settled down to about 350 degrees after idling for a bit but was just about 1000 when dragging the boat. the next morning we are talking monday now i wash the boat and then park the boat in the barn. the truck drags it around the yard just fine and seems to shift just fine. then today while driving to work empty it shifted just fine too. the tranny temp gauge hardly registers which is normal. the truck has about 85000 on it and this is the first time i noticed this problem. whats the consensus tranny problem or something else thanks for any tips. clint === . 222 307094 r3r6f.10529$cg.1818@02.roc.ny agreed. while a higher c.r. improves specific horsepower not always economy it cannot pull more hp out of the fuel than is available. go too far with cr and you will lose economy. its more important to burn all the fuel you can in the cylinder and low octane fuel actually burns faster than high octane. the water/alcohol system i used added a fuel in the form of alcohol vapor and the water vapor reduced the chance of detonation from a lean mix / excessive timing advance situation at cruise throttle. for example my 79 dodge d-150 with 318 ran 55 degrees advance at less than 40 mph mechanical and vacuum advances combined. normally vacuum advance doesnt come in under cruise throttle until 50 mph and yielded 20+ mpg from a vehicle with the aerodynamics of a brick but it would detonate under certain conditions. the 65 225 slant six otoh ran two light springs in the mechanical advance which brought full advance in at around 1000 rpm. on 87 octane this would be a massive ping situation under any load but it only pinged when i forgot to add mix to the bottle. in a 64 valiant it towed an overloaded u-haul trailer over monarch pass co 11000+ feet without strain and delivered 28 mpg at the time. the water / alcohol injection system was on that engine for over 100000 miles and during that time my worst fuel mileage was 20 mpg ... the point had burned up and i didnt have another set until payday the next weekend -- budd cochran warning!!! poster still believes that intelligence logic common sense courtesy and religious beliefs are still important in our society and may include them in his posts. budd cochran wrote to big al yes i read the article and if it were anymore vague it could be used as a soap-opera script. more hype about himself that about the carb and not enough about himself to determine if hes even a logical shadetree inventor. i printed out the pop mech article. the water injection they used works off manifold vacuum which drops as the throttle opened reducing vapor flow. a 5-10% improvement is about the maximum improvement and is about all you could expect * at best* . the system i used on the slant six drew vacuum off the distributor vacuum advance port vacuum increases with throttle opening delivering more vapor at higher rpm used an aquarium air stone 50/50 water alcohol mix and a heavily recurved distributor. full mechanical advance just above idle and full vacuum @ 4 inches of mercury iirc. budd on sun 16 oct 2005 164741 -0700 big al nospamsal1@qwest.net wrote a computerized overly complicated overly expensive way of injecting water into the intake flow. i see no verifcation of his 70 mpg claim nor any proof that he knows anything about combustion physics thermal dynamics fuel manufacture . . .no evidence hes anything but a charlatain. how does water injection help it allows a much leaner mixture by moderating the combustion process and preventing lean mixture detonation problems. it was commonly used in ww ii on many of our fighters to give higher power outputs under combat conditions. the moisture also flashes into low pressure steam to add to the power output. in 1970 mother earth magazine ran an article on how to build your own water injection system with an aquarium air stone a mayonaise jar and some vacuum line. add water and rubbing alcohol. on a 225 slant six in a 1964 valiant i got 41.25 mpg on a 145 mile round trip between canon city co and colorado springs co. the engine was running tighter than stock valve lashes mechanical lifters and a recurved distributor. otoh my eldest is now driving my old 1979 d150 318auto 3.55 axle long bed and getting 19 mpg around town and 23 highway but the vacuum advance has been seriously recurved. it also kicks 350 chubbie butt regularly. now what all this

cummins and redesigned the tranny yet again on 2005 models. re-designed the only change to the transmission that im aware of is an upgraded thrust washer under the front planetary to handle an exhaust brake.... that and some re-programming of the tcm for an ehanced tow/haul mode. .
