Yeah, they've installed my torque converter, my stage 2 valvebody, 3.91 limited slip differential, new half shafts and drive line. They installed my Wilwood big brake kit, they've installed heads, 2 cams (1st wasn't big enough....lol), oil pump, timing set.....Yada, yada, yada. They've done all the custom tuning on my car. They have a 4 wheel Dynomite inertia dynomometer. They are full performance service!!

You want a Diablosport Intune or Trinity tuner/programmer, they have them on site.

A torque converter can get you into your powerband quicker for better takeoffs and acceleration. A stage 2 valve body can speed up and firm up the shifting. With the valve body, the more aggressively you drive, the firmer the shifts.

If you think you might add more power, you might wait to get a torque converter. The optimum stall speed changes with the amount of power.

Thanks for the info, weighing options right now. Probably going to replace the Valve Body and see how that goes.

Bill, thanks for the tip on the Ditos. Solid guys.

Long story short, new Tranny. To be more specific, after being flushed three times with filter change etc as per the TSB relating to the miss-shift of third and fourth gears, the Tranny stranded David Dito on a test drive and the whining turned into slipping, and I'm sure anyone can envision the rest. So...a Chrysler Factory Remanufactured Nag1 with a 3 year/1000,000 warranty was the best and cheapest option at $2,250 + 4 Hrs.

Apparently upon removal of the bad Tranny, the culprit was FOUND! At some point, the previous owner (a mechanic) had removed the engine or Tranny and upon reinstalling, mounted the filler tube to the wrong location which caused the filler tube base to sit incorrectly in the housing and let water and contaminants in over time. So, in the end with the new unit installed, I realize how sluggish the old Tranny performed. Even though the new one is only a stock Factory Remanufactured one, the shifting is so much crisper and timely. No delay whatsoever.

Glad to be back on the road and thanks for all of the advice!

Brethren Magnum Owners,

I have a 2005 Magnum and recently found the transmission will not go into gears, e.g. 1,2,3, & 5. It operates in 'Drive' without any problems and automatically shifts gears by itself; although I like to downshift it to help stop at lights, shift off the line at the light, 1,2,3,4 & 5. I am not saying all the shifting is compromised; however it is not as fluid as before (which I loved). I can get to 1,2,3 & 4 but it won't go to 5. I can downshift to 4 but seem like I'm forcing it to get to 3,2 &1. Forcing it in my opinion can only lead to disaster.

From what I've gathered the transmission is a Mercedes design and gotta tell you prior to this problem it ran like a champ with lotsa power. I'm not too keen about being able to check the fluid level on my own. I have not received any 'idiot warnings' from the dash,...yet

Any suggestions??? I'm in Northern Virginia and do not have a favorite mechanic so I'm at the mercy of local shops. I'd hate to think this is an expensive transmission rebuild that will be a costly rabbit hole from one problem to another. From what I am reading this could be cumbersome.

Anyone with ideas pls give me a call (703) 989-7658 (James)

Hi all, Pretty brand new to this forum (and my Magnum) and having some transmission problems. Had to have my 05 R/T with 60,000 miles towed to my buddies shop today. Yesterday evening I noticed a high pitch "whining" sound when I would accelerate. Almost as if the car had a supercharger. It would happen in neutral as well as drive, after about 2,000 RPM. I thought it might be the serpentine belt or the belt tensioner causing the sound. However, on the way to my Buddy's shop to have him listen, I noticed the car losing power when I was accelerating and I pulled over just in time for it to completely lose motive power due to the transmission. Sure enough, it dumped about a pint of trans fluid on the ground and I had to have it towed. As well, it would not shift in any gears, nor show the numbered icons in the dash display when manual-shifted side to side. Question is, is the whole trans shot, or just just the torque converter or what? Anyone have any similar instances as this with the Hemi transmission? From my understanding, these transmissions are sealed and can only be accessed by pulling the pan without being able to check fluid levels from the non-existent dipstick? Furthermore, they are a Mercedes design as well right? My experience is all with the 918 and the 727. My friend who is my mechanic is a classic Mopar guy as well who knows his stuff, but doesn't have much experience with the new Mopes. Any ideas? Thanks in advance! -- Rich
Im actually having the same problem sadly but my issue is coming from the dipstick tube it’s self where it goes inside the transmission i replaced the seal & thought everything was ok but it happened again a short time after i went for a test drive trans fluid still pouring out I’ve ordered a new dipstick tube housing in hopes that, that would fix my issue also check your trans wiring bushing next to the dipstick housing for the trans tube if its the same it would have a brown top looks like a bottle cap but just larger.

I think it's a torque converter problem.
