9 Speed convertible transmission

I've ran into a lot of converted transmissions and they have no issues plus besides the shifter knob and one extra valve 9 and 13 speed are basically the same transmission as far as the d 13 goes make sure I think it's a reliable engine as long as you keep up with the maintenance they have some issues but to be realistic every truck has issues

 

Need to be sure it's a convertible too.....plenty running around that are not. better if it has the oil pump too.

Watch you dollars too. Converting is not cheap. you'll need a new back half and more air lines, a shifter and cut the shaft 3" if the truck is setup for a 9/10.

Check the side of the tranny too. If the Eaton plate is missing it been rebuilt by an outsider and very difficult to identify but in general build only. The bite comes when you have a large Cat needing 1800 plus ft lbs of protection and you get a 9 out of city tractor with a small pony rated at 1200 lbs. The Cat will shred the tiny tranny no matter what you do or how you drive.

Now I'm not a Volvo man, I run her cousin by marriage, the Mack. 780 is a nice truck but if you read in here, the D13 is not so hot.......

Good luck......

 

if it is a true converible 9 spd the tag on the trans will read something like RTLO169-9C, if it has a 9C on the end of the model # all that has to be changed is the shift knob and a couple airlines, it already has the backbox of a 13spd.it is a very good trans and as stout as a standard 13 spd. if it is a RTLO1699 then it has the small backbox and cant be converted easily. not familiar with the volvo engines but most of what i have heard hasn't been good. hopefully we cleared the trans thing up for you.

 

iv got it done. Kit was $180 @ local volvo dealer and labor was $245 . I love it , no problems so far.

 

• [h=2]Transmission Types[/h]
  • Eaton Fuller makes more than 260 types of transmissions. These are separated into 5-speed, 6-speed,7-speed, 9-speed, 10-speed, 11-speed, 13-speed, 15-speed and 18-speed transmissions. They are broken down into different model types.
    
    
  [h=2]Heavy-Duty Model Classification[/h]
  • Fuller designates transmissions by a code that contains letters and numbers. The letters in the code mean different model types. FR stands for Fuller Roadranger, R stands for Roadranger, T for Twin Countershaft, L for Low-Inertia Concept, O for Overdrive and X for Overdrive. The first character in every model number is T, for Twin Countershaft. The second and third digits stand for 100 nominal torque capacity. The fourth digit states the model's design level. The fifth and sixth digits are forward speeds, and the last letter is the ratio set. For example, RTLOC-16918B translates to a Roadranger Twin Countershaft, Low-Inertia Concept, Overdrive Convertible with 16 x 100 nominal torque capacity, 9th design level, 18 forward speeds and B for ratio set

If you get a 9 speed top 2 then the 13 speed conversion kit is around 300 dollars and takes about two hours to install. I found a transmission shop in Dallas that wil convert mine for 450 dollars.

 

Ok guys...correct me if I'm wrong....... doesn't the transmission HAVE TO BE CONVERTIBLE? And isn't that designated by a C in the pre-fix like RTLOC-XXXXX ?

Or did I miss something and all 9's are convertible ?

 

You're correct. It has to be convertible, and, if I remember correctly, they should already have the auxiliary box installed on them. It would be possible to convert a non-C transmission, but that would require the more complicated work you described earlier.. adding an auxiliary box, etc.

 

this really broke it down, great find....
