I have an 06 Chrysler 300 in possession waiting for Gieco's extended warranty to give me the OK to rebuild the 5 spd automatic trans and reflash the controller.It's a ZF 5 spd.The estimate is just over $3700.I did the same trans in an 03 320 sedan last week for a couple hundred less.It had water contamination,and the tcm was fine.I always run the VIN's to check if they have the latest software installed.
I've been doing quit a few of the ZF 722.6 trannys lately in a variety of vehicles because a lot of people are keeping their cars longer and the factory warrantys are over with.
I had been resealing a lot of the big HP24 6 speed ZF's in the Beamers.They all leak at the case pass through connector,similar to the V-Rods alternator wire leaking.I won't see many more of these because there has been a recall issued.
I don't keep up w what the rest of the world drives and likes.It takes a lot to keep up w what I do,and I just don't have the need to know what other countrys vehicles use for their drive trains,unless there is money for me to make from them.Then I become very interested.
Even in this poor economy,I don't do to awful bad for a one man show.Here lately,I've had some people in the biz call and ask me how I do it.I tell them,all I do is fix the customers complaints.This makes them happy,and keeps my electric meter spinning.
This one doesn't use planetary gears for the ratios.This is a constant mesh automatic.It's a Saturn TAAT.Same theory of operation as most Honda automatics.These are very critical for setting the end play and tolerance in the clutch packs.Sometimes .001 can cause bumps and bangs from one ratio to the next.
I've been working with automotive transmissions since 1977.They still intrigue me,and I hope they keep intriguing me for many years to come.
You know your gearboxes! But, that $3700 bill for that Chrysler slushbox is exactly
what I'm talking about. Tell me if I'm wrong but you could be in and out of an old three speed Torqueflite for under a grand. Is that ZF box really that much better? Just for grins, what would you
charge to rebuild an early 1990's Audi 5 speed manual, front drive only, no Quattro?
All this new technology looks nice on the brochure, drives nice when new and is comfortable to own when the car is still within the warranty period, but ten years and six digits on the odometer down the road, I'm not so sure I want one. How much specialized and expensive diagnostic equipment did you have to buy to reflash the ECM's that operate these new slushboxes? How much volume of business do you need to amortize the cost? I imagine that is driving a nice chunk of that $3700 bill.
Does any car really
need a seven speed transmission to perform well, or is it more a case of spec sheet warfare? I have similar reservations about the increasingly complex electronic systems and servo actuated BS on many high end motorcycles. Computers and software get out of date pretty quickly, and our vehicles are filled with computers and are run by software.
