Sumo Springs and transmission oil level?

HossHogRV · 02-26-2018, 10:51 AM

Solera R24 with (2014 Sprinter, 5,600 miles). Installed SSR-338-47 and SSF-106-40. On test drive transmission slips, RPM revs and jerks and clunks. Had not driven for a couple months prior to test ride.

Had RV towed to dealership and initial inspection showed transmission about a quart high. Waiting for someone to take a deeper look.

My question is has anyone else had this problem. At first I never considered the possibility that the bump stops could be the cause, but with the fluid level high, now wondering if having the front end higher could be the root cause.

Thanks

No problems with sumos for us, you may has a different transmission problem .

namusmc · 02-26-2018, 05:27 PM

No problem with rear Sumos here either, but please check back when you get a dx.

raptor · 02-26-2018, 08:15 PM

I can't check because there is no dip stick

I have the Sumos front and rear. I've had no problems. It is highly unlikely that they have anything to do with your transmission issue.

It's probably a shift in the glove box gasket. Lol

No connection between the two unless some enterprizing mechanic did something Very bery wrong.

I have Sumos front and back with no problem on my MB Chassis.

The sump on a transmission is deep enough to counter what you are suspecting, otherwise just climbing a long gradual incline would cause the same transmission issues that you are suspecting due to a higher front end. Doubt that the Sumo's have anything to do with it.

No problems 8K miles so far.

Where did you get Sumos for front? Easy to install? I have them for rear.

namusmc · 02-28-2018, 02:29 AM

Expanding further with dogpa's question, do the front Sumos demonstrate a significant handling improvement? In what way?

I use the rear Sumos and ideally like them being paired with the Helwig. Do you front SumoSprings owners feel they are cost effective from your driving experience using the Sumos?
I am contemplating installing the fronts, also.

Front sumosprings make a significant improvement in handling. I started with the rears then later added fronts. Further sway control but also much more level turning and cornering. Steering improved as the coach tracked better on highways, driving less "tiring ". Ride up front in the cab seems less jarring, the front sumo springs are softer than the rears. I would definitely put them on any sprinter

Thanks Rich! This will be my next project.

Good Morning, we just purchased a 24FW and I was wondering which sumo's you have installed. On there website they show two models the 336-47 and 336-54 for the rear. Any help would be appreciated.

Rich.M · 03-04-2018, 03:09 PM

I installed 338-47 rears

Rich.M · 03-04-2018, 03:12 PM

To the OP, what was the final diagnosis for the transmission problem

FFred · 03-05-2018, 10:36 AM

IF your Sprinter does not handle as well as you think it should,,

its time for the scales , then

before tossing parts at it a visit to a truck wheel alignment shop that can do "4 wheel alignments".

Yes they will measure/adjust the rear dual axle first , then do the front end.

The class C style MH is usually not aligned after construction , and the road trip delivery is not an inspection, its just some guy in a Big hurry .

When the chassis is 100% correct (tire pressure too) and it still has problems ,the aftermarket parts sellers are next..

Aftermarket help will be necessary if the unit is overloaded most times.

I have a 2016 W on a 2015 MB chassis. I installed the rear Sumo Springs (SSR-338-47) first, then installed the front Sumo Springs (SSF-106-40). Each set provided improvement in the ride and handling. The motor home handles like what it is, a loaded truck. I think the Sumos contributed to a more stable ride with a little less sway. I was interested in preventing the hard bottoming out of the springs when going over dips, etc. They smoothed out all of that too.

Update: Still not sure what caused the issue, but the dealership is replacing both transmission and torque converter under warranty (warranty expires 03/14/18). They could not determine what was the cause and opened a support case with Sprinter. During one of the test drives the technician reported that going 30 MPH it simply locked up, luck to have a seat belt. lots of debris in fluid. I never noticed anything until last month, returned from Maine (to Ohio) last fall and other than filling with gas it had not moved since. Very odd. Very glad this did not happen after warranty expired or while on the road.

Make sure they flush the transmission cooler and cooling lines.
