Please watch the video any input would really help. I have a 2006 Dodge 3500 4x4 DRW Edge Juice w/ Attitude, AFE Stage ll, 5" 1 Piece Drive Line, ATS Stage 2 Trans w/ Triple Lok TC. When backing empty or loaded this happens. I have put into 4wd and same, removed drive line and used 4wd ( front drive only ) and still the same. I have had 4 TC replacements and 3 Trans replacements. It is far worse as you see in video with trailer / load but does do it empty. Other than this the trans operates awesome. Any help would be helpful, again does it with rear drive line removed....makes no difference. Truck has 48k miles ( orig miles ) Thanks in advance.

Drop the pan and check the rear band adjustment. It might be loose.

 

I did that and that was unsuccessful we also tried installing a super servo and that was also unsuccessful I am at a complete loss but thank you for your input I truly appreciate it

 

Increase line pressure or just get a goerend constant pressure valve body! Hopefully the friction discs are still good.

 

Thanks for the reply. The builder is giving me another trans and doing mods to it to fit my needs better ( owning an RV dealership and always backing and towing ). I will keep you posted on what they did and how it works.

 

I had the same problem I'm a transporter of 5th wheel trailers. After putting in the Goerend valve body no more shutter! Been 100k no problems! Need anything taken to CA let me know!

 

I will for sure! Heading to Portland OR Saturday and was in LA for 2 others Tuesday. I may just need you!
