I’m starting to get a vibration at 1k to 1500 rpm feels like it’s coming from the torque converter now I’m getting delayed reverse when cold I’m pretty sure my gap was bigger than 3/8 could this be causing my problems?

@Camaro1524 Месяц назад

which Line from the Transmission goes to where on the Radiator?

@davidpowell1822 Год назад

Have you made more videos on your 5.3 swap including trans? A walk-around informative video would be awesome......gunshy on doing this to my prerunner ranger

@DownForMobbing Год назад

I can make one for you. Give me a list of things you’d like me to go over. Thanks for the comment!

@davidpowell1822 Год назад

Did you have to cut your firewall? What electronics? Any way to still run factory Guages? Would you have done anything differently?

@hetch1000 Год назад

And also what kind of budget should I be setting aside for such a transmission like you have for your package in your type of truck cuz I don't know which one you have I don't know yet

@jasonb2910 Год назад

for a really basic trans rebuild like i have its $1500 and that's just seals and a manual valve body with a 4ll60 hub on the inside.

@parkerd-qp6pn Год назад

So you need a 5/32" spacer, between 1/8" and 3/16" which is between 4/32" and 6/32". Seems a bit strange those spacers were not already installed between the original torque converter and flex plate.

@DownForMobbing Год назад

Nothing is original about this “setup” it’s a 5.3 motor with a old school th400. This setup is very common in the off-road industry. OE original vehicles have feet welded on the converter. Since these are custom built you have to do this

@hetch1000 Год назад

Quick question what truck do you have letter 1500 or 2,500 cuz that's what I got I got a 2500 93 pickup truck extra cab 3/4 ton with a 460 transmission

@jasonb2910 Год назад

my motor is a 5.3 LM7 out of a 2005 Yukon with a th400.

What did you use for insulation, and how is it working out? It looks great!

@DownForMobbing 10 месяцев назад

The tape did not hold on the edges but did hold on the flat areas where its butted together. Here is the video showing how the install of the insulation - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-o9GQMctmGGQ.htmlsi=aWVbyHRhgrl3dWCx

@hetch1000 Год назад

How does that help you and horsepower wise and torque cuz I'm really trying to get more torque I got a good power package but I'm losing a lot of so let me know how it helps and torque and power cuz I'm looking to convert ua4404 turbo 400

Th400 will kill about 40hp on a 500rwhp vehicle

@joshuas.4967 3 месяца назад

IN 3RD GEAR at wide open throttle the RPM's surge up and down up to 500 rpms! Could this be from incorrect spacing? It don't do this in 1st and 2nd gear, kind of odd, i am not sure what to try and repair.... NEW built TH400

@DownForMobbing 3 месяца назад

Sounds more like trans slipping but hard to say over the internet. 3rd gear is usually the first one to let go if it does.

@joshuas.4967 3 месяца назад

@@DownForMobbing Thanks for the reply! I am still investigating the issue.

@josecfish5297 Год назад

So I don’t want the 3/16 drill bit to fit? And does my gear ratio in my truck’s differential and wheel snd rim size affect the life expectancy of my th400?

@DownForMobbing Год назад

1/8 should fit and 3/16 shouldn’t fit. I am running 5.14 rear gear with 37s with no problems. Some trophy trucks are running a th400 with 40” tires with no problems. Make sure your pull out and fluid level is good and your trans should be fine. A lot of th400 problems come from shifting from 1st into 2nd gear at really high RPM.

This video is about blowing up trans. One in a half minutes into 4 minute video and I'm watching you install? Not just you but almost every human being that uploads videos: stop eating my time! Or, property lable video. Thanks in advance.

@DownForMobbing 8 месяцев назад

If you actually watch the full video I will show/talk about how people install a torque converter incorrectly and it will balloon into the pump and blow up the trans. That or it will pull on the pump. Those ARE THE TWO WAYs you blow up a transmission. Thanks for taking the time to watch and comment on this videos.
