Hey guyz,

As yall know, i have a 95 LD K2500. My trans started blowing fluid out the vent hose and feels like it is slipping in 1st and 2nd ( just a little though). Every now and then, when cursing on highway or accelerating, my truck starts to stubble, lose of power and feels like it going to stall. I have to put my foot down harder for it to down shift and the works normal (feels like the trans doesnt know what it is doing). Idk what this could be but thinking my trans is about to go. I also dont know the history of the truck pre 143k. It has air bags in the rear and seems to have 410s in the the pumpkins, so i am guessing it was used for towing. I am looking at transmission and was wondering if this would be a good one to buy. http://www.transmissionpartsdistributionin...995-1996/Detail

I dont really want to have a shop rebuilt trans bc the last one i had only lasted 30k miles before it took a dump on me. Besides, it is cheaper to and i can do the work myself. what do yall think?

These symptoms started this week and got worse friday night driving back to Richmond from DC

Don't forget to buy a new torque converter. Sounds like the old one may be stuffed anyway but you don't want to put an old T/C in front of a new trans....

Why not just get this one rebuilt?throw a stage 2 shift kit in it but get the transgo kit its better then the b&m i had both.Sounds like you overfilled the trans fluid and it just killed the clutches and to add to the problem you tv cable probably wasnt set correctly mine lasted 270k until 3rd started to slip.The first thing you should always check is the tv cable Thorttle valve cable or detent cable.If thats misadjusted the trans will not last long since its one of the pin points of line pressure.Good luck.Dont let them give you a price of 1000 dollars to rebuild it.I would get some prices for a rebuild but at the same call some junk yard for a anyother way i got one with low mileage for 300 with the TC and a 30 day warranty.Ooops just noticed you have a 4L60e sorry in that case no doubt look at rebuilding it.The prices and the chance of finding a good 4l60e is ot good anymore unless you have money to blow.

how do you check the tv cable? i know about the TC , i am just going to get a stock replacement one. I know for fact it wasnt overfilled when i had it. it was actually low when it bought then i change the fluid this summer.

What color was the fluid when you changes it? Did it smell burnt? Did you change the filter?

kmborland · October 30, 2011

normal red color. little darker bc of clutch material from normal use. nope, didnt smeller burnt and the mechanic helping said it was in great shape. yup, changed filter too. the truck only as about 11k since the trans fluid change. side note, i didnt flush the cooler lines or tc

I thought 2500's had the 4L80????

govtech · October 31, 2011

you dont have a TV cable .....

2500 light duty was basically a heavy half ton truck. shared the same engine, 4l60e, and frame as the 1500. The only real difference was SF 14bolt rear and a 7200 weight rating.

Thats what i thought, i dont have one.

No one really answered my guestion about the link i posted. Is that i good looking trans or should i look elsewhere?

I have a Performabuilt Transmission and could not be happier, cost to tear down and buy the parts my self and than not have a warranty far weighs out the cost for new with a warranty. Plus free shipping and no core charge..

1st.....I'm not convinced that you need a trans. Sounds to me like you may have a stuffed TC because of this statement,

----------------------------------

when cursing on highway or accelerating, my truck starts to stubble, lose of power and feels like it going to stall. I have to put my foot down harder for it to down shift and the works normal (feels like the trans doesnt know what it is doing).

------------------------------------

That is classic symptoms of a bad TC.

2nd.....Having your own trans built by a local professional is usually better/cheaper than buying a rebuilt unless you have broken hard parts in your trans. If nothing's broken (and sounds like nothing is broken) all you need is new clutches, servos and seals& gaskets...... A rebuilt may be more cost effective if you had broken parts in your trans.

You would be wise to replace the converter no matter what when going to a new or r/b trans so why not just install a new converter, filter and new fluid (flush the system good) and see if that doesn't solve your issue (unless you find metal in you pan)..

You may do well stopping by your local trans shop and letting them test drive and estimate the job for you. It's pretty hard to diagnose this stuff over the internet.

well, its not the TC, the tech told straight up when we were test driving it. its a fuel problem. says that my fuel pump might be going out. the still dont now why my trans is blowing fluid out the breather though. the tech says the trans is in great working order for how old it is. So i am actually going to have them run a test and see what they say. interesting though, looking for trans and finding out the weak points, i would get a monster trans when my trans goes. thanks for the help guys

When you serviced the trans, did you replace the trans filter seal?
