Houston area Auto Trans shop?

Looking for a transmission shop in the Houston area to take my GMC 2500HD to.
It's not broke yet, but it seems like something is slipping and I know nothing about autos. For example, backing up my parents driveway, not unusually steep, it won't even hold and will roll forward when in reverse. At idle in drive on a flat road, it doesn't quite go like the Ranger (granted the weight is a bit more).

Bought the truck wik 97000, now has 106000 so I don't know what previous maintinence has been done. I plan on at least having someone do a drain and fill, change the filter?, but would really prefer someone who knows what warning signs to look for instead of an NTB or such.

Thanks

You might call Latemodel Racecraft where we had our dyno day this year and see if he knows someone. I use a guy up here in Tomball called DSJ Transmissions. Did a great job on rebuild and upgrade on my Expedition, but he's all the way up here.

had a new trans put in mine just last year. be ready. if you have it rebuilt, put a new converter in it too. my bill was $2800.
i used Ace Trans here in DFW. they mostly do race stuff. there are some tricks that can be done to the 4L80E. once its all done, get a tune on the truck PCM to bump line pressure w/ the coverter locked. i had a 1-2 shift kit installed and bumped the line pressure for lock up as i trashed the clutch in the converter. the increase in line pressure will help stop lock-up clutch slippage. mine likely died due to towing the enclosed at 80mph. the converter just cant handle that load.

DSJ.. David St. James... old friend of mine... I've known him for over 25 years...

I bought a motor off of ebay and the guy sold me a late model chevy transmission for $100... it is suppossed to have a shift kit in it similar to what glenn was talking about... What tranny do you have?

all gas 2500's have the 4L80E. then in like 2006 or 2008 they went to the 6L80E. if its diesel, its the alison.

Well aren't you "special"...

That was his gas 2500 short yellow bus...

Gary's is a 6.0 and they came with the 4l80E.

Gary, what part of Houston are you in? I knew the owner of an Aamco in Houston near the astrodome that was a good guy. What matters is the warranty and the guy who builds it.
If you need a rebuild let me know as I would look into a reman unit. Think about buying one from the dealer and finding a shop to put it in. Look up scoggins dickey or a GM online crate motor place to see what they will sell you a reman. I might be able to hook you up with a Reman unit from the group we used to get ours from.

Let me know, I owned at Aamco for 5 years.

Call Transplus , Bob Butcher (713) 987-2228 Real nice guy and good pricing, knows his sh** may be able to get a hook-up....will find out

or call Houston Automatics (281) 890-4400‎

used these guys for a long time and have done great work


Either way call me with details so I can get you a quote from the first guy

832-317-8261

Yeah, it's the 6.0L.

So the general concensus is that fresh fluid / filter really won't fix anything and the proper fix is basically a complete rebuild/reman unit? Are these (1st post) the typical signs of a dying trans? Had 3 manuals die on me (2 clutches and one gearbox, all in different vehicles) and havn't had the pleasure of experiencing a dying automatic (knock on wood)

Was kinda hoping to get out on the cheap this round before the haul to Hallet. The $3G I had burning a hole in my pocket just went to a new A/C unit for the house :( May have to roll the dice and wait til later to get it seen to.

Thanks for the help. I'm in west Houston, work in Sugarland. BL and RS, I'll be contacting you tomorrow.

Sorry Rob, didn't mean to strike a nerve by talking about breaking transmissions and Hallet in the same breath. :D :D :D

What a great idea....who thought of that?


JJ

Jerry Jordan did - that's who!

I think the conversation went something like..

JJ - I sure would hate to get all the way to Hallet and have a transmission go out on me.

RL - Yeah, that would really suck. Hey, I've got a spare T-5, I'll check it out and see what it needs.

JJ - That sounds good. Us Mustang guys are really cool.

RL - Yeah - Camaro guys are nerds.

JJ - Especially Glenn - what a doofus.

Or something like that.

:P

its just like you Rob to kick a man while he's down on his luck......
