Expert:  kalamykid replied 11 months ago.

When it should shift from 2nd to 3rd, does it just hold on to second or does it go into neutral?

Have you had any work done on the transmission in the last two years?

Customer: replied 11 months ago.
Yea a full rebuild 3 years ago.
Expert:  kalamykid replied 11 months ago.

Do you know if they replaced the separator plate between the valve body and the case?

Customer: replied 11 months ago.
I dont know honestly
Customer: replied 11 months ago.
I just know they replaced the valve body
Expert:  kalamykid replied 11 months ago.

From what you have told me it sounds like the number 7 check ball has either blown through the separator plate or has gotten stuck in the hole. You need to have the valve body pulled and have the plate inspected. I it has blown through or is stuck in the plate, replace it and to help keep this from happening again install a trans go jr. shift kit. The kit will not make the transmission shift harder, but will update the valve body to give you a much stronger transmission as well as one that will shift much better.

Do i have to pull the transmition to do that. And what are the costs to take it in
Expert:  kalamykid replied 11 months ago.

No the trans does not have to come out to do this repair. A shop will charge you around $500.00 parts and labor.

Expert:  kalamykid replied 11 months ago.

This is a job you can do yourself if you have a basic set of tools, a jack and 4 jack stands. And the instruction sheet that comes with the shift kit is very good so you do not have to worry about making any mistakes. You can get your parts from www.transtar1.com , for around $150.00 plus you will need about 8 quarts of fluid.

Ok so what do i have to do im all ready to do it. Is there a youtube video or anything? I would rather do it myself
Expert:  kalamykid replied 11 months ago.

If you do this job yourself, get a tub of red trans jell to help you put it all back together.

Customer: replied 11 months ago.
Do you know if there is a video to do it? Or what are the steps?
Expert:  kalamykid replied 11 months ago.

Order your parts from transtar you need to order a separator plate, the shift kit, and a tub of red trans jell.

Expert:  kalamykid replied 11 months ago.

Once the parts come in, we can go over everything together on here.

Customer: replied 11 months ago.
Ok so can you send me an email so i can talk to you again?
Expert:  kalamykid replied 11 months ago.

All you have to do is come back to this string and send me a message. I will get back to you aspa, and you will not have to pay again.

Customer: replied 11 months ago.

Expert:  kalamykid replied 11 months ago.

All the parts you need will come from trans go. If you get them from trans star you should be able to get them by Wednesday.

Customer: replied 11 months ago.
