If you have used the TCI converter

[Power Wagon]

If you have used the TCI towing converter (non-lockup, of course), I'd like your input on how well it worked and perhaps some questions about some details... .





Appreciate all input.

I put one in mine when flex plate broke. Huge difference over stock. I've never driven a truck with a DTT or such. At the time wasn't real familiar with TDR and price was a issue. Tci has a number to their tech assistance etc. Will answer any questions i can. Stall speed is much lower.

I installed mine 3 weeks ago. Much better off the line response,probably cut initial throttle input by 50% or so. Haven't really taken a MPG reading yet,but it seem slightly better. Definately a good BOMB.

When I had my 95, I needed a better converter and bought a TCI. It was not machined right and tore up the front seal.

I called and they said send it back at my cost , they would investigate and let me know.

It came back 2 weeks later COD. So, I paid some one to change the converter out TWICE and paid shipping for their mistake.

I won't buy from them again.

Also it was still too loose for a Cummins.

My advice, FWIW, Is to buy it once and do it right.

Call Bill at DTT.

If either of you have a tachometer, I'd like to know the following:



What's the tach jump to when you mash it hard while standing still? I want to know how far the engine revs before it starts pulling REAL hard. Also, at 50 mph, kicking in and out the OD, what's the rpm change?



Thanks much!

Don't have a tach. wish i did. Not going to buy one. Maintenance only from now on with this truck. Next truck will be either new or a used 2003 hopefully.

 

[dodgenstein]

Sorry no tach either.

After I installed the TCI unit in my 93 I noticed two things right away - first was the stall speed was a little lower than before, and more noticable was that the engine actually dipped in the rpm's when the trans shifted. Before the engine would sit at 1800 rpm and never change rpm until it got up to about 60. It cruises at 70 mph at about 2000 rpm, and before you could bury your foot and the engine would just waste 300-400 rpm and get very little speed increase. Now if you bury your foot the turbo kicks in HARD and pulls to 80 in no time, and on up to 90 - then it runs out of rpm.

The engine actually runs at the same speed as before, but the stall in the converter when you want to accellerate is about 300 rpm lower. 70 mph = 2000 rpm, and mashed from 70-80 mph stalls at about 2150 rpm and levels out at about 2100 rpm. Big improvement on stall speed and power transfer, but nearly same rpm when not trying to accelerate.

Oh yes, also BIG improvement on hills. I'm towing the hot rod to the track next weekend, about a 3 hour trip each way, and I'll know for sure how much better it really works.



Full power pull stalls the converter at about 1600-1700 rpm, and gets up to speed quickly. Let's just say that for the $350 it cost for the converter I am very happy with the results. I also have a 12" TCI unit in my dually with a '63 big block 413 and a bulletproof 727, and it'll roast the tires if I really want to.

I have no doubt the DTT is the best out there, but for my needs the TCI is working great.

So, my two cents worth.

For under $350 it works much/much better then stock. To keep from hurting trans i only did this once on dry pavement but every now and then on damp pavement,turn a corner like leaving at a red light or rolling through a yield and hit throttle,,not even floored and can break both back tires loose easily and truck will spin and go sideways with no problem. Before with old convertor it would not. In fact will spin through second gear if dunked hard. Tci has been building circle track and drag convertors for years. At the time price was a issue for me also. If i had done the whole trans rebuild etc would have gone Dtt or Suncoast but truck was broken down two states away with flex plate broken and engine adapter gouged. Had torque convertor drop shipped to shop doing repairs.
