Winnebago 2000 5.9L cummins Allison Tranny

Hello


I find my *(new to me rig 2 Months) 2000, 5.9 Cummins, allison Transmission is a little lagging pep when it comes to climbing hills and can only get max 65MPH occasionally 70 MPH if declining a gradual hill.


I would like a little more pep in her step. Anyone got experience with tunes or getting more HP out of your rig. Advise or if you got more speed and HP.


Many thanks for reading and especially for any comments, information, opinions, musings or good vibes.

How much does your weigh ?

Are you towing anything ?

Do you know the current HP rating of your 5.9 Cummins ? 275 ?

What transmission does your coach have ? 2500 series or 3000 ?

Air and fuel filters new ?

How much does your weigh ? I will look that up. The GVWR is 24,850 I cant imagine I am anything near that as I have not added any weight over stock trim in MH and I pack light when leaving on a trip.

Are you towing anything ? I am not towing anything at the moment. I would be a little scared to pull anything. I would like to maybe next year.

Do you know the current HP rating of your 5.9 Cummins ? 275 ? Displacement (CC)5900.0 Displacement (CI) 360.04009015892 Displacement (L)5.9 Engine Stroke Cycles4 Engine Model B5.9/ISBEngine Power (kW)167.7825Valve Train Design Overhead Valve (OHV)
Engine Configuration In-Linek Engine Brake (hp) From225

What transmission does your coach have ? 2500 series or 3000 ? I will have to look that up on the transmission and do a little digging in the manuals.

I have all new air and fuel filters. I am picky and got my mechanic to run over it with a fine tooth comb. Replaced all belts oils even tranny fluid and filters when I got it.

Freightliner chassis of your vintage can have a fuel strainer in the supply line above the passenger side rear air suspension bag , a partially plugged strainer can cause all sorts of issues .
This diagram shows the location , hidden in wiring harness .

Easy to miss if you don't know where exactly to look .

The reason I ask about the transmission series , is that the lower series Allison transmissions ( 2000/2100/2500 ) are sensitive to the HP they can handle and chipping the engine can result in trans failure .

2500 series has a stamped steel oil pan and a spin on external filter ( red in the second photo ) ; 3000 series has finned aluminum sump and filters are internal in the sump .

Winnebago 2000 5.9L cummins Allison Tranny

I have same motor in mine with allison md3060 tranny. I added a banks kit, consisting of big hoss tuner, turbo hot side, and intake, cost was around $2500 several years ago. Also went from 3” to 4” exhaust and set turbo wastegate for 30# boost max.

Really increased power and fuel economy, pulls my 4 door jeep up mountains no problem. I could run 70 all day but my comfort speed is 62.

The main thing I was looking for was ability to pull most hills without tranny having to downshift from 6th all the time and of course the fuel economy. I got 8.5 last trip to Colorado and around 10 on flat lands pulling Jeep.

The Banks kit is a safe addition as the tuner automatically controls maximum EGT’s for you.

If you have the allison 2500 transmission it might not take the added power but the 3060 will no problem

You’ll want to keep your radiator clean, with the added power comes added heat. Mine does fine except pulling long mountain grades i have to downshift to keep revs up to assist cooling, she has more power than cooling capacity.

If its like my ex2000 36L, it has 275 hp with a Allison Mt tranny. That combination won't handle much more power than the 275.

I have a 2000 Journey, 5.9 Cummins, 4 speed Allison tranny, added a Banks kit, no longer available, FASS fuel system lift pump, and it does all I want now. I max out at 40 lbs boost, but seldom let it get that high. Don't want to blow off an intake hose. Whatever you do, don't starve that injector pump, a pain to replace, (ask me how I know), I highly recommend the FASS lift pump system. Made the most difference of everything I have done to the engine. 140,000 miles, still going strong, just keep blowing tires out. (Different post).

Yep I have an airdog and fuel pressure gauge on fuel line into vp44, as soon as the pressure starts dropping below 10psi under load im changing filters.

Hmmm Banks just sent me a new Big Hoss tuner not 2 months ago. I had issues with boost gauge occasionally dropping to 0psi but obviously still had normal boost. Power and egt’s normal. Happened several times since i bought it.

They finally sent me a replacement at no charge even tho I had bought it in 2019, awesome product support.
