TV (Throttle Valve) Cable Adjustment | 1st Gen Cummins
Вставка
- Опубліковано 21 лип 2024
- Today I show you how I adjust the throttle valve cable (TV Cable) according to the factory service manual for my 93 dodge w250 club cab diesel. I was having issues with delayed shift engagement and hard shifting. This TV cable adjustment drastically improved the drive-ability of the truck. The shift points occur sooner, the rpms stay locked while the truck speed increases and the power feels like it's being delivered to the ground much better than previously. I highly recommend checking your TV cable tolerance if you've got an automatic transmission.
Stay tuned for more videos!
Tyler,

Thanks Tyler, putting my truck back together after a full restoration. It needs this adjustment bad! Cheers bud!
Glad this one worked for you.Rather amazing how much a small adjustment makes.
I know I was really impressed how a small adjustment made such a difference!
Highway speeds are even more enjoyable with a 47RH and that sweet, sweet lockup. Good job on the TV cable adjustment. As I get my 47RH back into my build, I'll pay good attention to the TV cable adjustment as well.
If you're doing a 47rh conversion on a first gen, make sure you use the correct 46rh tv lever.
@@davidcole3927 I've actually got an aftermarket Lokar TV cable hooked up to the original TV lever so it operates just like it was on a 2nd gen truck. It was on my donor truck before the tear-down, and worked beautifully once I replaced the TV cable (original was locked up due to corrosion). But yes, if I were doing a new conversion I'd definitely use the original linkages and TV lever if they were available. That's good advice.
Maybe down the road one day.. this is supposed to be my beater truck after all..
Hell yeah, works great thanks, what I also did is I moved my top throttle cable, the one that’s like a ball joint to the next hole up on the mount, and moved my springs down to the bottom hole of the mount, and that also help with throttle responsiveness, cool easy free mod I learned from Decent Garage. Don’t think anyone ever adjusted the tv cable on my d250 till I did.
It's an awesome "free" upgrade eh?! Thanks for watching glad it helped out
I was having the same problem. Thank you so much
Glad it helped!
Thanks for the great video!!
I remember when I first did this adjustment as well. It's amazing!
Automatics are so finicky 🤣
So I started having problems with overdrive hanging up . I started at your other video .lol . Added fluid I was about a quart low and didn’t change much. Still hangs up trying to shift to od. Especially under load.
@@adrianmiles6271 did you adjust the TV cable like this video shows?
@@adrianmiles6271 you'll probably have to adjust your TPS. Tim has a good video on how to do that.
I checked the TV cab position and found that the spring was too weak to return it to the rear position. I changed the spring and it seems to be working shifting into od without the hang up . I’m going to double check the tps tomorrow just to be safe .
Glad I could help
If you set it up to where it shifts to early you won’t have enough line pressure to how can I say it to engage your clutch with your second gear ban and a high gear clutch pack and you can burn the transmission up because it all allow it to slip but you did good man I learn something from your video I had a problem with my old Dodge we put a different cylinder head of Hamilton cams head and head to modify the linkage bracket and all that I had to screw around get it to where I can shift early because it wouldn’t hardly shift at all anyway good job dude I like what you’re doing this is six in a row jim in Kennerdell Pennsylvania
This is awesome thank you for this video ima try to apply
Hope it works out for you as well!
Thank you for the descriptive video. Do you know if O'Reilly or Advance have this part? If so what is the part number?
What is the number one thing i can do to get a softer ride in my 1991 dodge d350 long bed single cab?
Good thing you were able to get it fixed. How well does that fiberglass sun visor reduce sun glare?
I think it's more for looks to be honest haha. Depends on the angle of the sun.
Having issues with getting the stop to keep gap where it needs to be .18" once i have adjusted it. Once I set the lock and actuate the linkage it goes right back to the original position which is about 1 1/4". The trans is not shifting from 3rd to 4th. I had the trans rebuilt 2.5 yrs. ago and it sat for two of those years. Don't think I have more than a 4k on the new trans. Help...?
3 to 4 is overdrive. My guess is either you have a pcm problem or your throttle position sensor needs adjusted or replaced.
Hey Tyler great video I've watched it a couple times now lol. I removed my cruise control one because I don't care much for cruise control at all and took the actuator out too on the inner fender. Anyways I've been trying to figure out where to put the spring because the previous owner moved the throttle linkage over to the inner slot on the throttle bracket so they just put both the springs on the bracket whereas there's no spring for the tv cable. Is yours the factory throttle bracket that rests against the idle screw? I think mine was changed in the past, but maybe I'll just crossover the spring to the outer slot on the bracket.
What I show in the video is factory the way my truck came. It didn't come with cruise control. If you take a look at some of the engine related videos on my red truck you might be able to see how it's setup on that one. That truck came with cruise control. You can always check the factory service manual too! Good luck.
@@OvensGarage Oh okay yea I see in your vacuum pump video I watched before how it's setup. It is crossed over thanks man.
Anyone selling one of these cables? I need it
Where can I buy a new one? I have looked everywhere, my TV cable is seized and restricting my truck from raving all the way.
Parts trucks or maybe try a Trans shop
Your wobbly tire noise hurts my ears. It’s like fingernails on a chalkboard 😂 all in all love the trucks love the videos keep ‘em coming. Hopefully this year 1 of the 3 trucks I wanna buy comes home with me. Been bugging these same 3 people for at lease 3 year now.
Haha, yeah they are noisy tires. They are re-treads so every time it hits the seam they make a loud thump..! They grip great though. Good luck with the trucks!
Compadre, Donde conseguiste la Información??
English?
He said were did you get that information . I guess the paperwork
@@cosanostra4286 factory service manual.
Me on the phone: Oh ya, fix yer TV Cable, it will make yer truck go faster, eh.
People around me: What is wrong with this guy?!
Is there anyway i could get you on the phone to pick your brain about my 92 a518
watching this i’ve realized that my TV is not only out of adjustment, but doesnt even have a return spring smh
Glad I could point that out indirectly haha
Same here but it seems to function decent without the spring
@@brycemanuel4205 It must be common. When I was adjusting mine the end of the return spring actually broke and fell off and I had to re bend it and put it back on.
2300 rpm! I would be doing 100 mph in my 92 Cummins
