grumpy1 I have a friend who bought one thinking he was getting the best. Its IS in a Show car, '55 chevy 2dr hardtop, not a race car. Nothing but trouble, No service worth anything, No warranty, just all junk. I would not buy anything from them. STAY FAR AWAY FROM TCI, THEY ARE JUNK DEALERS!!

I agree Stude, NEVER again.

Bayley Well, the new seperator plate made Z-E-R-O difference as I still continue to have no second or fourth gear.

I just got back from the transmission shop that has been working on this for me. The owner of the shop blew a temper tantrum and told me to get the car out of his shop ASAP. AFter I told him I would be happy to oblige... but I wouldn't be paying his bill, he quickly changed his tuned.

Also TCI is the most worthless company I've ever dealt with. I REALLY wish I could treat MY customers the same way TCI treats me... but then, even I'm not that vindictive.

Gonna go back to my original valve body and send this one back to TCI. I'm thinking about pooping in the box before hand though? Anybody think that's a bad idea... considering what I've gone through already?

eliotmansfield Ive spoken to Dennis before too.

Bayley Well, I got Jerry (manager of the sales depart) to come down to $40 for the seperator plate and gaskets.

I'm still annoyed that I ahve to pay for it, but I'm ready to swallow a little pride just to get this finished.
05-18-2006 02:02 PM
Bayley Well, this is definitely a step in the right direction towards finding the root cause for all this.

The next problem (that I'm currently having) is getting TCI to send me the plate and gaskets that were originally supposed to come with the kit.

I'm being told that I need the original invoice (which has long since been lost) sent back along with the contents of what originally came in the box.

For crying out loud, I've already lost $1000 in transmission shop repairs (new clutches and bands) because of the lousy TCI support, now they are telling me I need to shell out an additional $100 for a new plate and gaskets to be shipped to me.

I just can't win with TCI.

Also, Dennis (technical rep, 1-888-PRO-XTCI extension 334) was probably the RUDEST individual I've ever spoke with. I tried talking to him in a calm productive tone of voice, but he seemed convinced that I was trying to somehow scam TCI. I wouldn't think that a seperator plate and gasket set would put TCI out of business. He also mentioned that had I "originally followed the instructions like you were supposed to, you wouldn't need an extra seperator plate!"

What a tool.

Thanks again for the help guys... the saga continues.
05-18-2006 01:40 PM
eliotmansfield Well the contents for that kit http://www.tciauto.com/instructions/376010_inst.htm also list a plate.
Maybe we have an answer!?
05-18-2006 01:21 PM
Jmark Any chance the seperator plate is under all the crap in the box? My Transgo kit came with the sep plate under everything and even under a price of protective cardboard. Just a thought.
05-18-2006 01:06 PM
Bayley ...mine didn't come with a new seperator plate.

Also, I have the 376010 which is the valve body without engine braking. I'm going to call TCI right now and see what they have to say.

Thanks Eliot.

eliotmansfield TCI supplies a custom plate, it's red anodized.

The lack of pressure is your problem, on the test port for a particular gear, it should be the same as line pressure (i.e. well over 200psi) when that gear is selected.

You saying that you used your original separator plate?

The kit contents http://www.tciauto.com/instructions/376015_inst.htm states "1 Separator Plate"

Pressure drops to almost nothing (20 - 30 psi) whenever the gear selecter >= 2nd gear. Reverse, Nuetral, Park and 1st all have 230 - 250 psi. However, as soon as I drop it into second gear, the line pressure drops a couple hundred PSI.

Last night, I reinstalled the original valve body and everything works fine. I feel 99.9% confident that I've reduced the problem to the control circuit(s) in the TCI manual shift valve body.

Elliot,
Did TCI give you a new plate with your valve body, or did you re-use your existing one?

Yup. Sure do.

Any more guesses before I take old Yeller' out behind the barn with my shotgun?
