Any idea on the cost and difficulty in converting an manual 82 Trans am ( 4 speed ) to an automatic ?

 

Probably.Hard to say... brain surgery is easy for a brain surgeon, but hard for the rest of us (at least, that is, if we expect the patient to ever have a coherent thought afterwards.... ) All the same I don't think you'd want ME operating on YOUR brain.

It'd be a piece of cake for me, probably take about 3-4 hours tops if I had all the parts sitting there waiting. But I'm pretty slow, so maybe you could do it quicker?

 

Main question would be - WHY? Just about everyone else wants to swap out an auto tranny to a standard, why do you want to do the opposite?

Then i'd ask - Is the reverse gear in the forward left, or backwards left position ? That tells how desireable that 4 speed manual transmission is. If you've got your heart set on avoiding it, it might be worth a pretty penny to someone else. (If reverse is forward left you've got the winner).

 

just because I prefer automatic
not the winner because it's a backwards left position ( 4 speed Borg Warner)

 

Borg Warner = Super T-10, That's top left, IIRC.

Back left is Saginaw, and yea, Too bad.

You need a fair bit of parts that are probably somewhat difficult to find in france. Tranny, center console, shifter, pedals, etc. Is it necessary (standard died?) or just desired?
I'd guess you'd be in the range of $1000-$2000 when the smoke clears, probably on the high side.

 

Ok for the moment the cars is always in USA and I would like to buy parts before the car come in france.
YOu know if the big driveshaft (beetween transmission and "bolt") it's the same ? or if it's the same between TH200R4 (or TH700R4) and original Bolt (i don't know if it's a 9 or 10)

and sorry for my english

 

by "bolt" I think you mean "rear axle". It has either 9 or 10 bolts though. Yours, if it's the original one, will have 10 bolts.

Your driveshaft will be the same length if you go to a 200c transmission, and I think if you use a short tailshaft TH350. If you go to a TH700R4, or a 200R4, I think you need a different one, and perhaps a different transmission cross member as well.

mon francais est tres mauvais, donc je prefere parler anglais

Most of the parts should be fairly easy to get in USA, from a junkyard. Like I said, this swap isn't all that common, so the parts should be plentiful.

 

to me its more easy to put a automatic then a manual. right know i'm about to drop my 700r for a custom rebuild t-5 for me. the only problem u will have with the auto is reprograming it with ur comp if u have one. cuz if u put a different moter or cam in to it the trans. the trans it self will not know when to shift gear when u press the pedal to the metal

and Could you please tell me the lenght of the driveshaft mounted with a Saginaw 4 speeds gearbox and the lenght of the driveshaft mounted with an automatic 700R4 gearbox ??

thanks
