Yes, it had 35’s on it and I got rid of them and put stock tires on. That really helped to keep the EGT’s in check with the HY turbo. I am at 2000 rpm at 65 mph.

I recently bought a 28.5’ fifth wheel and have been getting the truck checked out to do some towing this summer. I changed the fluid and filter about 10k miles back and it was really clean. I might just be getting paranoid about the tranny. No indications of problems yet. The biggest load I have pulled is a 18’ trailer loaded with hedge firewood over a couple of passes in Co. Also, any correlation between tranny failure and gearing ratios? I have the 4.10’s so I am in overdrive at a slow highway speed.

What should the stock transmission fluid temp be when cruising? I just got my gauge back from Westach that has had the pointer stuck since I installed it. I have the sensor on the transmission line, not in the pan so I know it will be a bit cooler there. Haven’t gotten around to installing the port in the pan yet. Yesterday it was 45 degrees out and the temps indicated from 100 to 110-not towing anything. She rolled over 114,000 miles and y’all have me thinking my transmission might be getting short in the tooth.

Here is mine

It was listed as new but after I called it turns out to be a Cummins reman.

I just ran across a new HX35W Cummins part for $300. Is that a good deal or not?

One more question and I will shut up. Do you need or is it necessary to but the outer cover for the BHAF?

I don't think I can add a boost elbow to the HY unless I am missing something. I thought the boost elbow was for the HX.??

I bought it about a year and a half ago and didn't get gauges on until last winter but it has acted this way ever since I had a way of measuring the EGT's. I will check the intake-I have not checked that. Pack rats were a pain this year. Thanks for the tip. I did just look at the filter and it was clean as a whistle and I sure don't see it smoking when i get on it. I am too old to rip and romp the truck but don't mind working it when I need to. It has 107 K on it now. I have put about 11K miles on so far and a lot of it pulling a trailer.

I appreciate the help. I either need to stop being in a hurry or spend some money I think I will go ahead with the BHAF, see if that makes any difference, then decide what to do on the turbo.

20 PSI is about it on boost.

OK, I went out and tried to see how high I could go on the boost pressure and the needle wouldn't go any higher than 20 PSI. This was starting at the bottom of the hill without a load or trailer and giving it all she had. Is 20 PSI considered normal? Appreciate all the answers and comments.

With an HY?

No excessive smoke and most of the time I cannot see any smoke. 15000 gross, not pulling 15,000.

31" tires and can see high egt temps in 3rd or 4th. I have to drop my speed down to compensate for the temps like I am not working the engine at all.

That is good to know. I get nervous when I get close to 1200. I think I will try one at a time. 1) Boost elbow and BHAF 2) 4" exhaust if that does not help then the HX Turbo Thanks for the help guys.

I do have a Superchip Cortex and run it on 3 of 5. I have also set it back to stock and don't see much difference. I need to pay more attention but think my boost will show close to 30 PSI when in a hard pull.

If I stayed in it I could see 1300 pretty qiuck.

Yes, I keep my air filter changed probably too regular, sometimes every oill change. I have a lot of petal left during the climb and dont see much temp rise in the transmission oil temp when pulling a grade unless I am on a gravel road going slow.

So, leave the injectors as is for now? Any special connectors to adapt the post turbo exhaust? That is one question I have that I cannot find an answer to in my search. I also run 2 cycle. Thanks for the reply.

This may sound like a 1st grader question, but here goes. My 2001 with an HY turbo while pulling in the mountains will make the EGT's climb very qiuckly to the point that I have to back off and downshift to keep them in check. I have the stock exhaust, stock air filter, 47RE, 4.10"s Fass 95, gauges, stock sticks and oversized tires. I have searched this site looking for a remedy for to keep these EGT's in check. What I think I have gleaned is that I could swap the HY to a HX, put a aftermarket larger exhaust (by the way, my exhaust system has what looks like 2 mufflers or a cat and a muffler) maybe a BHAF and bigger injectors to help this situation. I just hate being passed by a Toyota Tundra pulling a camper on some of the grades or passes because I have to back off to keep the EGT in check while pulling a trailer grossing no more than 15K. I would like to know if I have interpreted what others are saying and also if I go to the HX turbo if I need to do anything special to mate up the exhaust system, so any help is appreciated. Thanks

A house cat could hide in the hole in my dash.

Wow, what a difference the new Bilsteins made in the ride. Looked like original shocks with 107,000 miles on them. Only problem will be the shiner on my right eye that I will have in the morning from dropping the 3/4 drive ratchet. Thanks for the help. I do plan to remove the leveling kit when I wear out these big tires.

I have been trying to figure out which shock will work for my truck and am not sure what to order for the front. I have a 2" leveling kit. I see that Rock Auto has 2"lift specified with Rancho's but it notes "dual" shocks. Any help is appreciated. Thanks

It includes the turbo and VP. I thought it sounded fairy cheap. May be more to it than is advertised. I saw it in an add in Garden City KS, just in case anyone wants to investigate. I don't need it, but if anyone is interested just let me know and I will give you the number.
