transmission works great

[iccon]

Over the last 2 years my tranny in my 03 h2 has not worked that greatest, the 3-4 problem and even 2-3 was not that solid so I talked to 3 tranny shops one said over the phone it needs a rebuild $3600.00 the other guy with a beer in his hand said it needs a rebuild $2800.00 and the last guy who has done work on one of my trucks in the past said its a cheap and easy fix, he said its not slipping just needs 1 new part and it should work fine. With that said 1 hour later and $200.00 spent my hummer has never shifted so well, nice solid shifts @ slow and fast accelerations my guy also said he cant say when the tranny will go but he said this cheap fix will prolong the life of the tranny he also said the factor new about the problem from the start and was to cheap to fix it hoping they would fall out of warranty before they need to repair them.

So what did he do to fix it?!

[ROUSHDEMON]

yeah really.... Teaser...
Its like the time my wife told me "I bought something you will love!" and hung up the phone....
:D

[iccon]

I just called the guy he said its call the 2-4 band servo, it was less then an hour to fix on the hoist, they are used in the vetts in the 6 speed trannies.

again works great

cheers

Not to doubt the OP but can anyone confirm this? It seems like a cheap and easy fix that may prolong the tranny. (of course, not so cheap for the original poster with an hour of labor and 15 dollar part. Guess that guy charges 185 per hour...lol)

A handheld programmer can stiffen up the shift patterns just the same

[funnone]

Just Ordered One!
Thanks for the info :dancingbanana:

[iccon]

Not sure of the part # but he did say there are used in the vett transmissions and that looks like the part.

No **** guys this thing works great just pulled my 5000 lb trailer and man what a differance in shifting, also just driving on the hwy and passing someone this thing moves. I like
cheers

[iccon]

[iccon]

If your tranny was already slipping...its not a fix, just a short term band-aid. How long you own the vehicle will decide if its your problem or someone elses.

Supercharger manufacturers recommend this, and shoddy auto dealers do this on weak trannys to firm them up for sale.

I was looking at these last month when I was thinking about finally putting the magnacharger on the truck. A link I saved on installing it-

There's a billet servo available that hold 35-45% more than the corvette, it can be found around $100.

Okay....This all sounds good. I like the idea of this. However They keep saying it's an upgrade for a 4L60E Trans. There is no mention of it beeing an upgrade for a 4L65E Trans??????? I will have to put a call into my father in-law he owns a tranny shop and still actually builds transmissions.

Iccon, would appreciate if u can get that parts#/brand from ur mechanic.

Thanks guys!

[iccon]

I will see if I can get part #

[[__--MUD--__]]

i believe 60, 65 and 70 are all interchangable.

[H2R]

700R4/4L60E/4L65E are all the same for the servo's for 2nd gear and 4th gear, and the seals for the servo's are the same as well.

What is the install process like? Is there a step by step on the forum?

If you read the thread, you'd see there's a install link already posted.

[iccon]

nice job on the install info MUD, but with that said I still would have had
Rick @ RS transmission do the work on my hummer because my servo was a bit seized on to the tranny.

maybe on the next one I will do the install.

[H2R]

Easy to dislodge it, compressed air to the fluid input connection and out it will come.

[pteam]

I have heard of this before but havnt done it. I got 4 h2 limos that seat up to 25 people 2 with over 100k miles. Is there anything that could be bad about this upgrade? Anybody else done it?

[iccon]

Update
I have had a 10% improvement in gas mileage and I have also notice that when I pull my trailer my mileage only drops by a bit now and in the past there was a big drop also it just pulls so much nicer.
:D

pteam it will help your limo's.

It is best to make this upgrade when tranny is new or rebuilt and it will take alot more HP and just plain old hard use. It will still help old trannies.

I happen to know a Vette specialist is how I learned about this in 2005. I had made recommendations in forum then but, they may not have made transfer to new site. He recommened that you go to Chevy place and get 2-4 servo from vette same year as the H2. This guy is in AR and has customers that ship their vette's from all over for just tuneups but, especially to have superchargers installed. He has always been a good source of info on the H2 drivetrain for me.

I think at any stage of the transmission life it would be worth changing, the cost on line now that i have found it is about $15.00 and about an 1/2Hour to 1 hour to fix if you have a host.
my guy did it for $200.00 and at that time i didn't know how to fix it but still worth it.

[Cazador]

Worth doing on a truck still under warranty or no?

[iccon]

yes as long as the dealer doesn't void warranty
