2001cummins

Well looks like I should of came to yall first before I bought into the whole lubricity testing done on this stuff a few years back. I guess I will use both back and forth till I run out, then will go back to my 2 stoke oil- like yall said lot easier to get your hands on. Live and learn I guess.

thanks, I was thinking the xl was mainly a lube like the 2 cycle oil was just was suppose to have an injector cleaner in it also- don't believe any cetane is added to that one. The only neg I see so far is the xdp has a strong smell similar to Power service stuff. The xl is not near as strong. Have to keep this stuff in the tool box unlike the 2 stroke I just keep it in the truck already pre measured out.

yes sir, you fellas know better than me. The 2 stroke is available almost anywhere and cheap but opti-lube and it is suppose to help keep your injectors clean at same time, and takes less per tank so it should actually be cheaper in the long run. Just figured I would buy a few gallons and test it out. Like I said seems to have smoother idle and less smoke. I just figured I would try it, I have read on other forums that guys running 2 stroke for 100k and more miles they have more build up on top of there pistons than normal than trucks running just straight diesel.- but this is just what I read, cant believe every thing you read on internet.

What are yalls opinions on opti lube I have been using it and seems to smooth out idle and motor seems to run better than with just the 2 stroke oil I have run in the past. It is little expensive but has better lubricity results from past studies

thanks, will look at that too. I did end up changing the fluid and filter over the weekend and while I was in there, I did find the 3-4 spring to be broke in half. Seems to shift better now but still late lock up but not as harsh. thanks for all the help from everyone.

Ok thanks, I was going to buy the master kit from cascade transmission parts that has all the solenoids and new gasket and 3-4 spring $200. Figured it would be worth it to see if that helped would be cheaper than taking to trans shop. But if you don't think that is the problem no point of wasting 200 dollars?

so could it be the solenoid going bad.

well looks like I need to get a different relay then, mine is just the basic relay you buy at autoparts store there is no resistor or diode diagram on the ones I saw locally. Where are yall finding a 30 to 40 amp relay with a resistor or diode built in.

not sure if it is stock or not, it had 160000 on truck when I bough it, He did not say he has had any trans work done to it. But when it locks up(what I am counting as 5th) it is a hard shift then does not ever come out of lock up unless I slow down, but truck has no problems downshifting it is always in correct gear if I slow down then take back off. Just don't remember any of my other cummins with auto tranny shift like that- but I guess from what yall are saying it may have different converter and valve body because it does not have any problems other than that. Timbo apps is suppose to be in tonight so I will put on and see if that helps- have read some other post that helped with there shifting on auto trans for some reason.

I also may try and switch relay to see if that helps. Ac noise was less than 0.024

Thanks for the help, yes it's stock as far as I know. I cleaned all ground wires in truck and seemed to really help. Now only gear that is harsh is 5th. And takes a while to let shift to 5th. Any ideas what would cause that

Yes sir will do. Will get back to yall after I get off this evening.

Sorry don't have a live data tool, might be worth investing in though if they arnt too pricey. What is the TV cable? Seems like it is the last 2 gears with the hard shifts

not that I can tell, it seems if I let off the throttle sometimes it will shift and some time I have to keep in the throttle to get it to shift. I did order a timbo apps to see if that does help at all.

I have a 2001 dodge reg cab 2wd with the auto tranny only bought about a month ago. It shifts great in the first few gears but the last 2 seems to hold till about 2000rpm and then shift pretty hard. I have checked the alt and am only about .024 ac volts. I am going to clean the grounds anywhere I see them. Fluid still looks brand new, but may replace and put new filter on. Any suggestions or has any one had same type of issues. Thanks to everyone so far for being helpful.

I am running a airtex lift pump and have my pressure gauge hooked up at banjo bolt coming off the injector pump. I was looking and Vulcan they sell a big line kit with a tee that I can mount the pressure solenoid. Just doing a 1/2 inch line from the fuel filter housing to the injector pump- would that be beneficial at all since the rest of my lines are all still factory. What are yalls opinion on this.

all I can find locally is a 30 amp relay. Will that work and then I can just use the 20 amp inline fuse going to it?

thank you, just got back into town and will wire up this evening.

and the black wire coming off the lift pump just goes to the ground correct

thanks, Sorry guys for all this. I am mechanical on trucks, but electrical on anything i just want to make sure. 1. So for my number 85 can i hook both my lift pump black wire to it also along with the ground wire that is coming from the ecu? 2 Where did yall mount the relay so it was out of the way and none of the wires can come unplugged? 3. 20 amp fuse is good?

thank you sir, that explains good enough to me to justify doing. one more question So the yellow/black wire- IS this one that is on the stock pig tail color-that connects to pump? Black/White wire- IS this one that is on the stock pig tail that connects to pump? - These two can just be cut and then wire to relay box? then 87 you have going to fuel pump. will this be just the red wire off my lift pump and then ground the black wire on the fuel pump somewhere?

Sorry for the dumb questions but I will admit I am electrical challenged. the advantage to this is it takes the load off the ecm. so have many people had problems with this and this was best solution. Just trying to see what advantage this has over factory- can the factory ecm not handle the load? Also where are yall mounting all this for a stock pump location on engine.? I have learned a lot on this site in the last month or so and just trying to do what is best for the longevity of my truck.

is this only for aftermarket pumps that don't use the stock wire harness. I am using an airtex in stock location and just plug the pigtail into the pump?

ok thanks, yes it is summer compared to most up of yall up north. Its 80 degrees this week in the dfw area.

good deal, thanks for the help, I am sure I will be asking for more help later down the road.
