Hi check the colour of your transmission fliud is it should a medium red if it looks dirty brown or any other colour that would suggust your clutchs are slipping if your transmission fluid is low or over filled it will cause your problem you can drain your fluid remove your lower sump pan clean the boxes main body and filter replace the oil and try there is no gaurentee it will work but this is a basic you can do and these type of repair can resolve your problem if the fliud is brown then this and an adjustment of of the boxes clutchs and bands must be done this can be done with the transmission in sitution there are other things that can cause the problem but these are well worth doing first as it will not cost a fortune and has a good chance of success yates210456

How to flush a transmission fluid on a 98 gmc jimmy

I would not recommend flushing trans fluid you risk
getting debris into the solenoids

You will get people telling you other wise

I just remove the pan clean it & refill

If a trans is old it may slip if get all the fluid out
by flushing

You drive a couple weeks then if it is okey you
drop the pan & change it again & that time change
the filter

I did once own a trans repair shop, I'm giving you
my opinion on 48 years personal experience,not
as a former business owner.

You change trans & power steering every 3 years
& never go over 30,000 miles on any vehicle

Use the correct fluids & NO ADDITIVES

You lost reverse band will need to have the back part of the transmission torn down to repair, if your lucky it will be about $450.00 or if not it will be about $1600.00 for a complete overhaul. They have a problem with the rear main shaft seal. You may also may get lucy with just being a bad servo or stuck piston or a shift lever out of adjustment.

99 jimmy transmission no reverse...will transmission flush solve problem

Once reverse is no longer working the transmission usually needs a total rebuild. If it was one of the forward gears only, it would be a different problem, maybe one of the electronic solenoids. I had this problem on my 2000 Blazer and went through all the motions. So I talk from experience, and had to replace the transmission. Good luck!
