transmission

Is it possible to convert a 18918B to a 20918B transmission if so what needs to be done Thanks in advance

As of July 1st if you take your ministry truck road test in an automatic truck you will have a restricted license. Here is the article.. https://www.trucknews.com/regulations/ontarios-restricted-class-a-licence-to-come-into-effect-july-1/1003166936/ Should you be worried about drivers that have...

I have a 2020 Peterbilt 389 with 18 speed transmission. When shifting from direct to overdrive the transmission shifts in hard when I let off the accelerator. Peterbilt said o rings leaking oil and replaced them. Still doing the same thing.

What are the shift patterns for the RTXF12609B and RTXF1209P? What are the differences between these 2 transmissions?

Is the 15 speed RTO14615 transmission good for highway use? What is the transmission’s average speed range ?

I have a 2018 Peterbilt 367 tri- axle with an 18 speed with 32000 miles 510 horse. When I am in say 5th Direct and switch to over drive the engine does not come down any RPM it jumps into gear jumping the whole truck. Took it to Peterbilt they replaced the regulator and O-ring, If it was O-ring...

I have a 2019 Fredlighner Cascadia, which accidentally broke transmission air tank. I put new air tank but the engine won't start because its telling me to put gear in neutral. I can't put gear in neutral because there is no air in the new tank. How can I let air into truck from outside? or can...

Just picked up a freight liner 2 axle truck with a C13 cat. It has the 10 speed smart shift automatic transmission. This is a 2007 truck I am looking for some tips on driving this thing as it relates to the automatic transmission. So far from what I can tell I HATE IT!!!! It will only start...

My 2019 579 with PACCAR drivetrain has been intermittently going into transmission fault mode when moving it around to docks. This is new since the last service? Seems to have to do with shifting before it completely stops? Anybody else have this issue?

Truck runs and shifts perfect. I can go through all the gears with no problems but when I use the transmission and engine brake to slow down there is a loud grinding noise coming from the tranny or the drivetrain somewhere. It does it through all the gears and goes away as soon as I take the...

Good day all. Perhaps someone has experienced this. I have a 2010 vnl780 with a D16 and a ishift. For the last few weeks I completely loose my pedal. My tranny says it’s in gear but I cannot use the throttle. After a few seconds it comes back. Any suggestions? Thanks

I wanted to get advice and help troubleshooting an ECM issue we're having. So I'll give you quick backstory on the bus. It's an 09 International 3200 with a Maxxforce DT engine and the Allison 3000 pts transmission (vin: 1HVBTAAN09H096575, Miami 1st half of its life, Houston the 2nd half. The...

So I got my CDL B about 4 or 5 years ago and ended up 'grandfathering' into having no restrictions (the automatic transmission restriction I mean). Here's the problem I'm having... The company I wanted to start working for is swift, and they use manual transmissions. The school that I went to...

Guys, I have this issue of tranny not going into gear with low air pressure. I'm not sure what area is the problem. It only happens in the morning (2 days now), The secondary air pressure is zero and primary has some. I start the engine and primary never goes above 70 psi and secondary about...

I have a 93 RD Mack. My transmission rattles when in gear mostly coasting round 55 mph. I know differential noise can travel. But when I knock it out of gear it stops. If it was in differential wouldn't it still rattle? Could it be in transmission?

Transmission running hot what could cause this to happen

I have a 2014 388 with a 600 cummins with a 18 spd 2050 . There is a rappen or knocking noise in the transmission when pulling a loaded trailer. You can hear the noise after you have driven about 50 miles bobtail. Notice the noise when you accelarate bob tailing or loaded every gear. Press the...

My trucks selector switch has been making a grinding noise when I select to low gears after using the high gears. Two days ago I noticed a massive leak. It looks like it's coming from the top of my transmission.

I recently rebuilt a Mack T310M transmission on a 2007 CV713. It worked great for 3 weeks and on the 4th week I had a grinding noise on all gears. I took it back and the transmission was taken apart and everything was check, Then it was rebuilt. Had the same problem. Also a new clutch was...

I want to buy a new transmission. I will need to have mine worked on sooner than later. My clutch brake is next to worthless right now. I will need a clutch soon. I am thinking about upgrading my transmission. Currently, I have a Eaton Fuller RTOC-16909A, it has been converted to a 13...
